K mean clustering of image

Hi All,
I am exploring the LabVIEW machine learning toolkit available at https://decibel.ni.com/content/docs/DOC-19328.
I want to try the unsupervised k-means clustering on an image to segment it.
I have a color image of an apple. I want to be able to segment the defects on the surface based on the difference in the color using K means. There is a brown patch on the surface of the apple, I want to be able to segment it out using k means.
However I am unable to figure out how to proceed. I checked the examples provided with the toolkit however, they dont use images.
Has anyone worked on this toolkit? Any guidance can be very helpful.
Thanks.
Regards.

Hello,
looking at the image you've posted, it is going to be difficult to segment the brown patch reliably. You should first make sure that the camera is focused properly and perhaps you could somehow use additional lighting to your advantage.
But anyway, see an example of image segmentation based on K-means clustering (using the Labview machine learning toolkit) here:
https://decibel.ni.com/content/blogs/kl3m3n/2014/10/15/color-image-segmentation-based-on-k-means-clu...
I have just posted this in response to your post. I hope you don't mind and that it will be of some use to you (and others).
Best regards,

K-means clustering

I am trying to k-means 10000 cluster on 500000ross having 42 attributes but it gets failed.
please post the comment

Dear Sir,
In my database table kdd contains 500000 rows and 43 columns, and i want to cluster it using k- means, in advance setting of build stage i put
number cluster = 10000 and Minimum error tolerance = 0.1 , maximum iteration = 2. But after 75% it get fails and it takes alot of time also.
version:10.2.0.3.1 (build 479)
There is no failure message after 2-3 hours it get fails.
Please give me your valuable suggestion.

Using K Means in a Calculation View

Hi Experts,
Can you please help me with the below scenario.
I am trying to use K-Means function to perform clustering on customer data. I have the below columns:
Attributes:
Customer ID, Home Ownership Status
Measures:
Customers Debt to Income Ratio, Annual Income
1. Is it possible to use multiple attributes given above to perform the clustering as i read that clustering can be only done using measures.
2. I need to pass the number of clusters dynamically from report to the K-Means function to perform clustering. I tried to use calculation view to get this parameter from user at runtime and pass to the input parameter table of K-Means function. But the problem is, calculation views will not allow any kind of DDL statements like create/drop/insert/delete/update etc.
3. Further i would like to understand how to use the results of the K-Means clustering delivered via two tables one having clusters, distance and other having clusters and remaining measures to build a scatter chart. How this can be achieved.
Please help.
Thanks and Regards,
M.N.Adinarayanan

Hello,
Would you share your dataset maybe I can help.

Clustering in java

I know this is not a specific problem related to java, but I am looking to implement in java some sort of clustering algorithm to cluster points on a map. Was just wondering if anyone had any experience in this, or knew of any good related wen pages.
Thanks for your help

For clustering low dimensional data (like 2-d map coordinates) your best bets are "k-means clustering" and "agglomerative hierarchical clustering". Both are fairly fast, not difficult to implement and produce reasonable results. Google for details, I imagine there are probably java implementatins out there somehwere.

About n1000v with port channel

there is a n1000v connected to multiple upstream switches in the customer's production environment.
the following is from the Cisco Nexus 1000V Interface Configuration Guide, Release4.2(1)SV2(2.1).
You use vPC-HM mode to create a port channel when the switch is connected to multiple upstream switches
that are not clustered.
my question is,
can I use LACP with multiple upstream switches that are not clustered?
can I use LACP with multiple upstream switches that are stacked?
if I stack multiple upstream switches,does it mean clustered?
thanks.

Hi,
See some of the guidelines:
Guidelines and Limitations
Port channeling has the following guidelines and restrictions:
•All ports in the port channel must be in the same Cisco Nexus 1000V module; you cannot configure port channels across Cisco Nexus 1000V modules.
•Port channels can be formed with multiple upstream links only when they satisfy the compatibility requirements and under the following conditions:
–The uplinks from the host are going to the same upstream switch.
–The uplinks from the host going to multiple upstream switches are configured with vPC-HM.
•You can configure multiple port channels on a device.
•After you configure a port channel, the configuration that you apply to the port channel interface affects the port channel member ports. The configuration that you apply to the member ports affects only the member port where you apply the configuration.
•You must remove the port security information from a port before you can add that port to a port channel. Similarly, you cannot apply the port security configuration to a port that is a member of a channel group.
•You can configure ports that belong to a port channel group as PVLAN ports.
•Any configuration changes that you apply to the port channel is applied to every member interface of that port channel.
•Channel member ports cannot be a source or destination SPAN port.
That said LACP should work on switches that are not clustered and meet the conditions above.
A stack is treated as one unit which means that would be like you have just one big chassis.
Stacking does not the same as clustering it works different. so if you stack them that would be a stack not a cluster

Hope this helps.

Laptop battery problem?

Hello, I have a big problem and That battery starts my laptop: http://www.dearbattery.co.uk/compaq-presario-cq71-battery.html , And the laptop (only 7 months old by the way) you can not start! Now my question is, HAS something to do with the charging cable (there still burns the green light, Which means clustering something like that comes from the power repays Seckdose) or something on the laptop, or is it broken?

please take the laptop for the hp service center you will get a solution

How to use the apply procedure for partial classification

Hi all,
I have used the Oracle data mining association rules (AR Apriori) to build a model which I filter out its rule to include only those where the consequent (RHS) is the class attribute. This enable me of producing partial classification rules set(associative classification) even though I have used AR model. The question now, I want to apply the module to test data using the APPLY procedure, however, AR unsupervised learning models are not supported in the APPLY procedure.. Any idea how I can over come this problem....
I notice that there are similarities between AR and K-means clustering algorithm, the question, can I convert an AR model into a clustering one?
Thanks in advance
F

The short answer is no. It is not possible to move the model content from one model to another. The only way to do that would be if you knew the internal representation of the models and could then change them directly. This information is not documented. If you managed to do that, you would not be able to get support if you run into problems with those models.
Out of curiosity, why you want to use AR to build a classifier instead of one of the classification algorithms in ODM? I have seen some work on associative classification. It seems that these approaches usually try to get around the greedy top-down nature of decision trees by first identifying regions (itemsets, rules) with reasonable frequency and then prune to create a classifier. The numbers I've seen were not very convincing for the extra work and ad hoc nature of those methods.

Dominant color and color mask

Hi,
1. How to find which is the dominant color in an image,which method can be used to find it ?
2. How to apply color mask to an image?
Thank you
Mdhubalan Panneerselvam

Hello Madhubalan,
maybe this can help you get some ideas about finding the dominant color. I am attaching a VI that uses three different methods to determine the dominant color:
1. Red or green or blue (only one of the three, no colors in between)
2. Hue based histogram
3. K means clustering based (you need to install the library from clustering)
The first method returns only red or green or blue value based on the maximum values of the rgb planes.
The second method uses a hue histogram where the rgb values are recalculated. The problem here is the saturation and luminance - the code takes the mean values of both, so its off sometimes.
The third method produces most acurate results, as far as i have been testing it.
If you like, you can test the code, but maybe someone with more experience than me can provide a better solution.
Anyway, I hope this helps you to proceed in the right direction. Aslo, sorry for the dirty and unoptimized code.
I do not understand what did you mean with the color mask?Could you please explain in more detail?
Best regards,

Does anyone know how to remove rain from static shots?

I tried doing the pen tool frame by frame but it degrades the image. I tried doing a gain reducting but all it does is blur features and not even remove the rain. I looked up a computer science journal that gave a method with K-means clustering but I don't know how to apply it to AE...any advice, ive been stuck on this for days...thanks

Wanna post a sample of that vid for download somewhere? Also... "frame by frame.... remove the rain"
You mean 2 droplets right?

Removing noise in optical motion capture data

Hello to you.
I am building my own optical motion capture system. In
relation to this I have coded a modified K-means clustering
algorithm in LINGO, which can be used for removing image noise in
the captured image data. Noise is in this case regarded as being
sparse groups of pixels (e.g they do not belong to a marker as
these are represented as compact pixel groups).
In order to evaluate the performance of my algorithm I need
to compare it with some other noise filtering solution. Does anyone
know if there is any suitable such LINGO code available? Possibly
Mean or Median filters…
I hope for positive replies:)

The problem is that you're deleting things from the list
you're looking at
and things get moved towards the start, thus skipping an
iteration you
wanted to examine. If you start at the end, you won't get
that problem.

How we make 10000 clusters using k-means in ODM

Probably it's a resource issue. 10.000 cluesters sounds like cutting it pretty fine. What happens if you go for a lower number of clusters, like 100? Is it an option to form 100 cluesters and then subcluster each of those into further 100 clusters, or 10 into 1000 or some other combination?

Advice Requested - High Availability WITHOUT Failover Clustering

We're creating an entirely new Hyper-V virtualized environment on Server 2012 R2. My question is: Can we accomplish high availability WITHOUT using failover clustering?
So, I don't really have anything AGAINST failover clustering, and we will happily use it if it's the right solution for us, but to be honest, we really don't want ANYTHING to happen automatically when it comes to failover. Here's what I mean:
In this new environment, we have architected 2 identical, very capable Hyper-V physical hosts, each of which will run several VMs comprising the equivalent of a scaled-back version of our entire environment. In other words, there is at least a domain
controller, multiple web servers, and a (mirrored/HA/AlwaysOn) SQL Server 2012 VM running on each host, along with a few other miscellaneous one-off worker-bee VMs doing things like system monitoring. The SQL Server VM on each host has about 75% of the
physical memory resources dedicated to it (for performance reasons). We need pretty much the full horsepower of both machines up and going at all times under normal conditions.
So now, to high availability. The standard approach is to use failover clustering, but I am concerned that if these hosts are clustered, we'll have the equivalent of just 50% hardware capacity going at all times, with full failover in place of course
(we are using an iSCSI SAN for storage).
BUT, if these hosts are NOT clustered, and one of them is suddenly switched off, experiences some kind of catastrophic failure, or simply needs to be rebooted while applying WSUS patches, the SQL Server HA will fail over (so all databases will remain up
and going on the surviving VM), and the environment would continue functioning at somewhat reduced capacity until the failed host is restarted. With this approach, it seems to me that we would be running at 100% for the most part, and running at 50%
or so only in the event of a major failure, rather than running at 50% ALL the time.
Of course, in the event of a catastrophic failure, I'm also thinking that the one-off worker-bee VMs could be replicated to the alternate host so they could be started on the surviving host if needed during a long-term outage.
So basically, I am very interested in the thoughts of others with experience regarding taking this approach to Hyper-V architecture, as it seems as if failover clustering is almost a given when it comes to best practices and high availability. I guess
I'm looking for validation on my thinking.
So what do you think? What am I missing or forgetting? What will we LOSE if we go with a NON-clustered high-availability environment as I've described it?
Thanks in advance for your thoughts!

Udo -
Yes your responses are very helpful.
Can we use the built-in Server 2012 iSCSI Target Server role to convert the local RAID disks into an iSCSI LUN that the VMs could access? Or can that not run on the same physical box as the Hyper-V host? I guess if the physical box goes down
the LUN would go down anyway, huh? Or can I cluster that role (iSCSI target) as well? If not, do you have any other specific product suggestions I can research, or do I just end up wasting this 12TB of local disk storage?
- Morgan
That's a bad idea. First of all Microsoft iSCSI target is slow (it's non-cached @ server side). So if you really decided to use dedicated hardware for storage (maybe you do have a reason I don't know...) and if you're fine with your storage being a single
point of failure (OK, maybe your RTOs and RPOs are fair enough) then at least use SMB share. SMB at least does cache I/O on both client and server sides and also you can use Storage Spaces as a back end of it (non-clustered) so read "write back flash cache
for cheap". See:
What's new in iSCSI target with Windows Server 2012 R2
http://technet.microsoft.com/en-us/library/dn305893.aspx
Improved optimization to allow disk-level caching
Updated
iSCSI Target Server now sets the disk cache bypass flag on a hosting disk I/O, through Force Unit Access (FUA), only when the issuing initiator explicitly requests it. This change can potentially improve performance.
Previously, iSCSI Target Server would always set the disk cache bypass flag on all I/O’s. System cache bypass functionality remains unchanged in iSCSI Target Server; for instance, the file system cache on the target server is always bypassed.
Yes you can cluster iSCSI target from Microsoft but a) it would be SLOW as there would be only active-passive I/O model (no real use from MPIO between multiple hosts) and b) that would require a shared storage for Windows Cluster. What for? Scenario was
usable with a) there was no virtual FC so guest VM cluster could not use FC LUs and b) there was no shared VHDX so SAS could not be used for guest VM cluster as well. Now both are present so scenario is useless: just export your existing shared storage without
any Microsoft iSCSI target and you'll be happy. For references see:

http://technet.microsoft.com/en-us/library/dn440540.aspx
Storage options
The following tables lists the storage types that you can use to provide shared storage for a guest cluster.
Storage Type
Description
Shared virtual hard disk
New in Windows Server 2012 R2, you can configure multiple virtual machines to connect to and use a single virtual hard disk (.vhdx) file. Each virtual machine can access the virtual hard disk just like servers
would connect to the same LUN in a storage area network (SAN). For more information, see Deploy a Guest Cluster Using a Shared Virtual Hard Disk.
Virtual Fibre Channel
Introduced in Windows Server 2012, virtual Fibre Channel enables you to connect virtual machines to LUNs on a Fibre Channel SAN. For more information, see Hyper-V
Virtual Fibre Channel Overview.
iSCSI
The iSCSI initiator inside a virtual machine enables you to connect over the network to an iSCSI target. For more information, see iSCSI
Target Block Storage Overviewand the blog post Introduction of iSCSI Target in Windows
Server 2012.
Storage requirements depend on the clustered roles that run on the cluster. Most clustered roles use clustered storage, where the storage is available on any cluster node that runs a clustered
role. Examples of clustered storage include Physical Disk resources and Cluster Shared Volumes (CSV). Some roles do not require storage that is managed by the cluster. For example, you can configure Microsoft SQL Server to use availability groups that replicate
the data between nodes. Other clustered roles may use Server Message Block (SMB) shares or Network File System (NFS) shares as data stores that any cluster node can access.
Sure you can use third-party software to replicate 12TB of your storage between just a pair of nodes to create a fully fault-tolerant cluster. See (there's also a free offering):

Hope this helped a bit :)

QMASTER hints 4 usual trouble (QM NOT running/CLUSTEREd nodes/Networks etc

All, I just posted this with some hints & workaround with very common issues people have on this forum and keep asking concerning the use of APPLE QMASTER with FCP, SHAKE, COMPRESSOR and MOTION. I've had many over the last 2 years and see them coming up frequently.
Perhaps these symptoms are fixed in FCS2 at MAY 2007 (now). However if not here's some ROTS that i used for FCP to compressor via QMASTER cluster for example. NO special order but might help someone get around the stuff with QMASTER V2.3, FCP V5.1.4, compressor.app V2.3
I saw the latest QMASTER UI and usage at NAB2007 and it looked a little more solid with some "EASY SETUP" stuff. I hope it has been reworked underneath.. I guess I will know soon if it has.
For most FCP/COMPRESSOR, SHAKE. MOTION and COMPRESSOR:
• provide access from ALL nodes to ALL the source and target objects (files) on their VOLUMES. Simply MOUNT those volumes through the APPLE file system (via NFS) using +k (cmd+k) or finder/go/connect to server. OR using an SSAFS such as XSAN™ where the file systems are all shared over FC not the network. YOu will notice the CPU's going very busy for a small while. THhis is the APPLE FILE SYSTEM task,,, I guess it's doing 'spotlight stuff". This goes away after a few minutes.
• set the COMPRESSOR preferences for "CLUSTER OPTIONS" to "Never copy source to Cluster". This means that all nodes can access your source and target objects (files) over NFS (as above). Failure to to this means LENGTHY times to COPY material back an forth, in some cases undermining the pleasure gained from initially using clustering (reduced job times)
• DONT mix the PHYSICAL or LOGICAL networks in your local cluster. I dont know why but I could never get this to work. Physical mean stick with eother ETHERNET or FIREWIRE or your other (airport etc whic will be generally way to slow and useless), Logical measn leepin all nodes on the SAME subnet. You can do this siply by setting theis up in the system preferences/QMASTER/advanced tab under "Use Network Interfaces". In my currnet QUAd I set this to use BUILT IN ETHERNET1 and in the MPBDC's I set this to their BUILTIN ETHERNET.
• LOGICAL NETWORKS (Subnet): simply HARDCODE an IP address on the ETHERNET (for eample) for your cluster nodes andthe service controller. FOr eample 3.1.1.x .... it will all connect fine.
• Physical Networks: As above (1) DONT MIX firewire (IPoFW) and Ethernet(IPoE). (2) if more than extra service node USE A HUB or SWITCH. I went and bought a 10 port GbE HUB for about $HK400 (€40) and it worked fine. I was NEVER able to get a stable system of QMASTER mixing FW and ETHERNET. (3) fwiw using IP of FW caused me a LOAD of DISK errors and timouts (I/O errors) on thosse DISKs that were FW400 (al gone now) but it showed this was not stable overall
• for the cluster controller node MAKE SURE you set the CLUSTER STORAGE (system preferences/QMASTER/shared cluster storage) for the CLUSTER CONTROLLER NODE IS ON A SHARED volume (See above). This seems essential for SHAKE to work. (if not check the Qmaster errors in the console.app [see below] ). IF you have an SSAFS like XSAN™ then just add this cluster storage on a share file path. NOte that QMASTER does not permit the cluster storage to be on a NETWORK NODE for some reason. So in short just MOUNT the volume where the SHARED CLUSTER file is maintained for the CLUSTER controller.
• FCP - avoid EXPORT to COMPRESSOR from the TIMELINE - it never seems to work properly (see later). Instead EXPORT FROM SEQUENCE in the BROWSER - consistent results
• FCP - "media missing " messages on EXPORT to COMPRESSOR.. seems a defect in FCP 5.1 when you EXPORT using a sequence that is NOT in the "root" or primary trry in the FCP PROJECT BROWSER. Simply if you have browser/bin A contains(Bin B (contains Bin C (contains sequence X))) this will FAIL (wont work) for "EXPORT TO COMPRESSOR" if you use EXPORT to COMPRESSOR in a FCP browser PANE that is separately OPEN. To get around this, simply OPEN/EXPOSE the triangles/trees in the BROWSER PANE for the PROJECT and select the SEQUENCE you want and "EXPORT to COMPRESSOR" from there. This has been documented in a few places in this forum I think.
• FCP -> COMPRESSOR -> .M2V (for DVDSP3): some things here. EXPORTING from an FCP SEQUENCE with CHAPTER MARKERS to an MPEG2 .M2V encoding USING A CLUSTER causes errors in the placement of the chapter makers when it is imported to DVDSP3. In fact CONSISTENTLY, ALL the chapter markers are all PLACED AT THE END of the TRACK in DVD SP# - somewhat useless. This seems to happen ALSO when the source is an FCP reference movie, although inconsistent. A simple work around if you have the machines is TRUN OF SEGMENTING in the COMPRESSOR ENCODER inspector. let each .M2V transcode run on the same service node. FOr the jobs at hand just set up a CLUSTER and controller for each machine and then SELECT the cluster (myclusterA, hisclusterb, herclusterc) for each transcode job.. anyway for me.. the time spent resolving all this I could have TRANSCODED all this on my QUAD and it would all have ben done by sooner! (LOL)
• CONSOLE logs: IF QMASTER fails, I would suggest your fist port of diagnosis should be /Library/Logs/Qmaster in there you will see (on the controller node) compressor.log, jobcontroller.com.apple.qmaster.cluster.admin.log, and lots of others including service controller.com.apple.qmaster.executorX.log (for each cpu/core and node) andd qmasterca.log. All these are worth a look and for me helped me solve 90% of my qmaster errors and failures.
• MOTION 3 - fwiw.. EXPORT USING COMPRESSOR to a CLUSTER seems to fail EVERY TIME.. seems MOTION is writing stuff out to a /var/spool/qmaster
TROUBLESHOOTING QMASTER: IF QMASTER seems buggered up (hosed), then follow these steps PRIOR to restarting you machines.
go read the TROUBLE SHOOTING in the published APPLE docs for COMPRESSOR, SHAKE and "SET UP FOR DISTRIBUTED PROCESSING" and serach these forums CAREFULLY.. the answer is usually there somewhere.
ELSE THEN,, try these steps....
You'll feel that QMASTER is in trouble when you
• see that the QMASTER ICON at the top of the screen says 'NO SERVICES" even though that node is started and
• that the APPLE QMASTER ADMINSTRATOR is VERY SLOW after an 'APPLY" (like minutes with SPINNING BEACHBALL) or it WONT LET YOU DELETE a cluster or you see 'undefined' nodes in your cluster (meaning that one was shut down or had a network failure)..... all this means it's going to get worse and worse. SO DONT submit any more work to QAMSTER... best count you gains and follow this list next.
(a) in COMPRESSOR.app / RESET BACKGROUND PROCESSES (its under the COMPRESSOR name list box) see if things get kick started but you will lose all the work that has been done up to that point for COMPRESSOR.app
b) if no OK, then on EACH node in that cluster, STOP the QMASTER (system preferences/QMASTER/setup [set 0 minutes in the prompt and OK). Then when STOPPED, RESET the shared services my licking OPTION+CLICK on the "START" button to reveal the "RESET SERVICES". Then click "START" on each node to start the services. This has the actin of REMOVING or in the case where the CLUSTER CONTROLLER node is "RESET" f terminating the cluster that's under its control. IF so Simply go to APPLE QMASTER ADMINISTRATOR and REDFINE it. Go restart you cluster.
c) if step (b) is no help, consult the QMASTER logs in /Library/Logs/Qmaster (using the cosole.app) for any FILE MISSING or FILE not found or FILE ERROR . Look carefully for the NODENAME (the machine_name.local) where the error may have occured. Sometimes it's very chatty. Others it is not. ALso look in the BATCH MONITOR OUTPUT for errors messages. Often these are NEVER written (or I cant find them) in the /var/logs... try and resolve any issues you can see (mostly VOLUME or FILE path issues from my experience)
(d) if still no joy then - try removing all the 'dead' cluster files from /var/tmp/qmaster , /var/sppol/qmaster and also the file directory that you specified above for the controller to share the clustering. FOR shake issues, go do the same (note also where the shake shared cluster file path is - it can be also specified in the RENDER FILEOUT nodes prompt).
e) if all this WONT help you, its time to get the BIG hammer out. Simply, STOP all nodes of not stopped. (if status/mode is "STOPPING" then it [QMASTER] is truly buggered). DISMOUNT the network volumes you had mounted. and RESTART ALL YOUR NODES. Tis has the affect of RESTARTING all the QMASTERD tasks. YEs sure you can go in and SUDO restart them but it is dodgy at best because they never seem to terminate cleanly (Kill -9 etc) or FORCE QUIT.... is what one ends up doing and then STILL having to restart.
f) after restart perform steps from (B) again and it will be usually (but not always) right after that

As FCP2 arrives in our shop, we will try once again to make sense of it and to see if we can boost our efficiencies in rendering big projects and getting Compressor to embrace five or six idle Macs.
Nonetheless, I am still in "Major Disbelief Mode" that Apple has done so little to make this software actually useful.

Cisco Jabber Client for Windows 9.7 Can't Connect to Other IPSec VPN Clients Over Clustered ASAs

Environment:
2 x ASA 5540s (at two different data centers) configured as a VPN Load Balancing Cluster
Both ASAs are at version 8.4(5)6
IPSec VPN Client version: 5.0.07.440 (64-bit)
Jabber for Windows v9.7.0 build 18474
Issue:
If I am an IPSec VPN user…
I can use Jabber to another IPSec VPN user that is connected to the same ASA appliance.
I can’t use Jabber to another IPSec VPN user that is connected to the different ASA appliance that I am connected to.
In the hub-and-spoke design, where the VPN ASA is a hub, and the VPN client is a spoke; if you have two hubs clustered together, how does one spoke communicate with another spoke on the other hub in the cluster? (How to allow hairpinning to the other ASA)

Portu,
Thanks for your quick reply.
Unfortunately, I do not have access to the ASA logs nor would I be permitted to turn on the debug settings asked for above. I might be able to get the logs but it will take awhile and I suspect they wouldn't be helpful as this ASA supports thousands of clients, therefore, separating out my connection attempts from other clients would be difficult.
I can, though, do whatever you want on the Linux router. Looking over the firewall logs at the time of this problem, I don't see anything that looks suspicious such as dropped packets destined for the Windows client.
As I said in my original post, I'm not a networking expert - by any means - but I am willing to try anything to resolve this. (But I might need a bit of handholding if I need to set up a wireshark andor tcpdump.)
Thanks again.
