SDK 3.1 UIImagePickerController access real time image

Hi,
SDK 3.1 has a much better UIImagePickerController. It claims that you can access the real time image without closing the controller. Could anyone tell me exactly how to access the image?
Thanks

Is vision development module in labview 8.6. sufficient for real-time image acquisition and analysis using a webcam

Hi,
I'm new to labview and trying to develop an eye-tracker using labview 8.6. It has the vision development module and i was wondering if this was sufficient for real-time image acquisition and processing or would i be needing any other software tools.
Solved!
Go to Solution.

Hello, certainly it is possible and sufficient for real-time tracking!
About eye tracking - if you need an example, you can find the code here:
https://decibel.ni.com/content/blogs/kl3m3n/2013/10/08/real-time-face-and-eye-detection-in-labview-u...
The code uses OpenCV functionalities along with the LabView UI (and some other functions like overlay).
Hope this helps a bit.
Best regards,

Converting Thumbnails to real time images

Some how I have deleted all my photos from my Mac Air & when I recovered it, all photos turnup into thumbnail. Is their any we can convert Thumbnail into real time images?

Thumbnails are real images but only smaller. There's no way to up size them to get back to the size the orignals were.
You're best bet is to restore the library from the backup copy made just prior to this happening.

How to display images real-time?

How, (using CVI, NI-IMAQ and IMAQ Vision) can I duplicate the Grab function seen in MAX; in other words, I want to display images at the frame rate of my camera (30 fps). I've come across several examples on this site, the best of which seemed to be "Performing Real-time Image Acquisition, Averaging, and Logging" (realtime_image_averaging.zip), but this example, built with LabView, can't find several vi's (IMAQ WindDraw.vi, IMAQ Convert.vi, IMAQ Add.vi, IMAQ Divide.
vi, IMAQ WriteFile.vi) needed to run it. I have LabView 5.1, NI_IMAQ 2.6 and IMAQ Vision for LabView 4.01). Please note that, although I'll accept LabView, I prefer a CVI solution.
Thanks in advance for any help.

I would strongly recommend upgrading to the current version of Vision. There have been major improvements since the version you have. I suspect the examples have improved significantly also, which would probably be worth the cost of the upgrade. I have attached a simple grab and display example in LabVIEW that I saved to LV 5, but I can't be sure it will work with the old version of Vision. Since you want to use CVI, it probably won't do you much good anyway.

Parallel computation - real time analysis

Im dooing real time image analysis, however my analysis program is the bottleneck at the moment so i want to increase its speed. Since I need an increase of about 60-80% the only solution would be dooing the analysis in parallel on a dual core cpu (currently running on AMD64 3700+).
The most time consuming computations in my program are two convoluitons so my idear is to have them running in parallel. I want to grab one image, do the first convolution and then send the result to a shift register. Next the program should (in parallel) grab a new image and to the convolution - and do the second convolution on the first image.
Is this possible?
As you can see in the attached vi Im trying to transfer the images in shift registers is this the right way?
How do I do the wireing of the error correctly?
How do I make sure this can actually run in parallel?
Hope someone can help me.
Simon
PS: This version of the program does not grab images, it just loads in previosly saved images. That way I can test the results.

Hi, if you want to have thoses convolute functions running in parallel, you will need to give them their own independent error in. That means the seconde convolute function shouldn't get its input from the first one.
I have modified your code so the two convolute functions are now running in parallel. From the attached result.jpg I can see a improvment at the VI execution time.
But I'm not sure about result, it seems that somthing is missing from the output array.
Please let me know if you have found a better solution to this problem.

Real time importing images

I am working on the project that I need to import images in real time. I mean my program have to get a picture per second.I am very new with LabView and don't know how can I do that. can anyone help me please?
Thank you in advance.

There is usb camera and I mean by real time is really fast like one picture per second. I am good at programing but no experience with LabView. Do you think can I code separately in C or C++ and kind of using in LabView.
I have a USB camera mounted on my monitor "looking at me". I fired up MAX and tried to determine how quickly I could "snap" (take a single image) pictures. Since I was manually "pushing the button", it was tricky to tell, but it seemed to be possible to take 1/sec. I then tried "grab", which takes videos -- this was (of course) much easier, and considerably faster (I'd guess tens of frames/second).
I have the Vision module installed, and am using IMAQdx for getting the images. LabVIEW isn't bad in capturing images, but there's not a lot of hand-holding or extensive documentation -- I think it could be a real challenge to "do it yourself" with no LabVIEW experience.
To even see if this is a viable approach for you, see if you can repeat what I did -- plug in your USB camera, open NI-MAX, and see if the camera shows up. If it doesn't, stop -- you don't have the LabVIEW software appropriate to do this installed.

Detecting PDF-image files in real time

Hi,
I'm planning to build a web application that allows users to upload PDF files. I want to be able to check the PDF files in real-time to ensure they only upload PDF text-searchable files, and not PDF image files. Is there anything from Adobe that has this functionality?
I'll probably to integrating it into a .NET web application.
Thanks.

Hi Leonard - thanks for the reply.
I've read up more about Adobe LiveCycle ES and it seems it might be a bit of an overkill for what I'm trying to do. I just need to have some software to check the PDF document whether it is text-searchable or not. LiveCycle appears to be a full document management and processing suite. Is there any more basic Adobe software that can do this kind of check?
Thanks much.

Why can't read access log file in real-time? (Oracle Weblogic Server 10.3)

We can't read access log file in real-time. If access log is rotation to new file so can read access log file but can't read real-time.
*** Oracle Weblogic Server versions 10 R3

what's your meaning? try this command "tail -f access.log".
Threre is a buffer about 8K for WebLogic to write the access info into the log files, so you can't see the access info untill the buffer is full.

Bug: Built Real-Time app won't run if it accesses a typedef'ed shared variable node

Hello,
I finished developing a Real-Time program that uses typedef'ed (clusters and enums) networked shared variables (SVs). It works fine when I run the program in Development mode. However, when I built and deployed it as a start-up app, it refuses to start. The VI monitor in the Distributed System Manager says that the VIs that use those SV nodes (and the top-level VI that references them) have "Bad" status, and the rest are "Idle".
To get my built program to run, I had to disconnect all the variables from the typedefs. Deleting the SV nodes made the program run too, but that's not an option.
Has anyone else encountered this?

Yes. See the following thread.

About DTP with real-time access.

Hello Gurus,
       setting for error handling only has an impact while repairing a DTP request (repair) and during the conversion of the DTP to standard DTP (for example, to correct an error during extraction).
      will you please give a simpel scenario to explain above words?
thank you very much.

Hi,
Use :
With SAP NetWeaver 7.0, SPS 14, the following changes and enhancements are available for real-time data acquisition:
●      Changes to the menu and the context menu of the monitor for real-time data acquisition
The menu and the context menus for the individual objects in the monitor for real-time data acquisition have been standardized and enhanced. In particular, it is now possible to assign daemons and data transfer processes on various levels using context menu entries. For a complete overview of the functions in the menu and in the context menus, see Monitor for Real-Time Data Acquisition.
●      Assignment of daemons for InfoPackages and data transfer processes (DTP)
To assign InfoPackages and data transfer processes to a daemon, you can call the monitor for real-time data acquisition in the following ways:
○       In the Data Warehousing Workbench using the respective context menu entry Assign RDA Daemon.
○       In InfoPackage maintenance using the Schedule tab page, and in data transfer process maintenance using the Execute tab page.
The button names for jumping to the monitor for real-time data acquisition have changed here. To jump to the monitor, choose Assign Daemon.
●      Repair process chains for repairing a broken data transfer or a missing delta in the DataStore object
In certain situations, a gap in the delta of the DataStore object can occur if there is a closed request in the PSA but there is no corresponding request in the DataStore object. For example, this is the case if a DTP request has terminated due to an error in the transformation. Here, you can create a repair process chain to repair a missing or broken update from the PSA. The repair process chain contains a standard DTP as well as any further processes required for subsequent processing (such as activating the data in the DataStore object or subsequent process chains). When the repair process chain is executed, the complete delta is loaded from the source into the DataStore object and processes for activation and further processing are executed if required.
●      Process types for starting and stopping real-time data acquisition
You can use process chains to control real-time data acquisition using process types Start Real-Time Data Acquisition (RDA) Load Process and Stop Real-Time Data Acquisition (RDA) Load Process.

Cannot check real time access while creating infopackge

Hi all,
I am getting an error while trying to create a real time infopackage. I have made my datasource real time by changing the real time flag in ROOSOURCE but while creating the infopackage the real time check is greyed out.
I had read in some other message in SDN that you can make non-real time DS into real time by changing the flag in ROOSOURCE any ideas.
Also we are in content 7.0.3 and I dont see any business content either in ECC or BI in ROOSOURCE table with real-time flag marked X. Does SAP delivery any content which are real time or am I missing something here?
thanks for your input

Hi Raj,
You can create the Real-Time infopackage only after creating the info-package for Init Load. The check box for Real-Time is not enabled if Initialization load is not run. Though this check has to be made only after creating the Real-Time Datasource correctly.
Go to RSO2, enter the datasource name, and open it in edit mode. Then choose the option 'generic delta'. Give the field on which you want the Delta pointer to be set (The field you want to enter here should <b>NOT</b> be hidden from SAP BW). Importantly, check the option 'Real-Time Enabl'. save the datasource. It becomes Realtime. Replicate the datasource.
Hope this helps.
Thanks,
Praneeth.

Problem with Real Time Data Acquisition

Hello,
I tried to built a RDA data flow according to the SAP-Help and this blog (/people/kamaljeet.kharbanda/blog/2006/11/13/real-time-data-acquisition-bi2004s), but I ran into a problem. Everything seems to be fine, but even though the daemon is running no new data is added to the DSO. I'll explain in detail what steps I took and hope someone can pinpoint my error(s).
System is BW4 on SPS 17. My datasource as well as my DSObject are in the same system
1.) Created a transparent table with a timestamp-field for generic delta as a local object.
2.) Created a generic datasource from view/table (used the above table), marked it as realtime-enabled and used timestamp as delta-specific field.
3.) Replicated the metadata for my datasource and activated it.
4.) Created a Data Storage Object with infoobjects corresponding to the table fields
5.) Created a transformation between DataSource and DSO
6.) Created a DTP from Data Source to DSO. The type is realtime-DTP.
7.) Created an InfoPackage for Delta-Initial Load. Update mode: Initialize Delta Process -> Initialization with Data Transfer.
8.) Then I changed my DTP (step 6) to "normal DTP" and executed it. Then activated the data in the DSO. The datasets from the table (which i filled with an ABAP-program) were successfully loaded and activated. So now my DSO contains 5 datasets.
9.) Changed the DTP back to "realtime DTP"
10.) Created an InfoPackage for RDA. Adapter is set to "Realtime extraction from SAP System"
11.) Created a daemon, assigned the IP for RDA and the DTP to the daemon and started it up.
12.) Executed my ABAP program to added 3 datasets to the table which is used as a datasource.
So now in my source table there are 8 datasets, but the daemon won't load them. In my RDA-Monitor (trx rsrda) it shows my daemon, the assigned IP and the assigned DTP (status green). Under the IP there's one yellow request (that should be right according to the help), but unlike the picture in the blog (link see above) there's no request under the DTP.
Job overview (sm37) shows an active batch job and some jobs that are ready (every 10minutes a new batch starts and the old one is closed). the job log shows, that the daemon runs, but loads no data...
i think it might be a problem with the delta extraction somewhere, because the intial load works fine and there are no errors anywhere.
Edit: perhaps my settings in the data source unter tab: extraction are wrong?
Delta process: AIE After Images By Extractor (can't change that)
Direct Access: Allowd
real Time: Real-Time DA Supported
Adapter: realtime data extraction (also tried Access to SAP Data through Service API which seems senseless)
Data Format: Fixed Lenght
Anyone can explain what those fileds mean and which one i should use?

Hi again, another thing i'd like to try is to just active a business content datasource which is realtime-enabled and has the ability to dynamically add some values so that i can test if it works. but i have no idea what business content would be applicable here, any ideas on that perhaps?

Speedgrade 7.2.1-direct link-GPU-real time color updates?

Hello,
Adobe says that SpeedGrade 7.2.1 now takes advantage of the GPU when Direct Linking a sequence out of Premiere.
Questions:
1. Does this mean I should see color corrections update in real time in my scopes and monitors the same way I see real time color updates in a native ircp SpeedGrade project?
2. I have a Black Magic DeckLink 4K Extreme card. Can SpeedGrade use my 4K card, or handshake with Mercury Transmit, so that I can get either an HDMI or SDI video signal output to my monitor?
3. I notice that for Premiere, adobe officially certifies GTX 690 for windows, and GTX 680 for Mac. Does this mean GTX 690 is not supported for Mac?
4. I tried right clicking on the SpeedGrade app, opening packet contents, and adding gtx 690 into cuda approved card list. That didn't seem to help. I did not try to amend the Open CL card list document, would that help?
Here is my system config:
Mac Pro Tower Early 2009
2 x 2.66 6-core Intel Xeon
48GB RAM 1333 DDR3
Cards:
Mac system report says all three of these are GPUs, however, my tech guy says the 640 is for GUI.
1. NVIDIA GeForce GT 640 (slot 2)
2. NVIDIA GeForce GT 690 (PCI Lane width x16)
3. NVIDIA GeForce GT 690 (PCI Lane width x16)
Cuda driver 6.0.37
Media storage is a raided 9TB serial ATA, about 300mbs read and write. Hard drive is even faster.
Adobe if you are listening, I'm trying to add SpeedGrade to my tool belt, especially since you did such a good job integrating the Tangent Element. The whole point of using SpeedGrade, as opposed to Resolve, is that the Premiere sequence links. I have access to everything, except AE comps.

Alright folks...I'm so close.
So, recap, getting real time performance and color updates using Direct Link in my external scopes and monitor, now that I'm on a Z800, windows 7 64 bit, with Quadro 4000, Cuda driver 394, AJA LHi card and break out box.
However, some problems still:
1. My internal SpeedGrade scopes are just a group of funky dots that kinda resemble my external scopes, viewing the same signal. Computer monitor resolution is 1920x1080. Tried other display options, still funky dots. Not a biggy, since external scopes are fine, just curious as to what's up with that? Is it because I'm using the latest Cuda driver 394, instead of an older one, since 4000 is old?
2 Do I need a LUT for SpeedGrade to output an HDMI video and SDI video signal in Rec709 2.4 gamma? Is it the handshake with the AJA LHI? Looks like it's spitting out sRGB 2.2 right now. I imported bars that I made in Symphony. These bars play out fine in Symphony and Resolve, through the same signal path SDI to the same monitor. However, in SpeedGrade whites are lower than a 100 and blacks are lifted. Since the bars in the external monitor look very similar to computer monitor, I'm assuming SpeedGrade is spitting out sRGB signal. Can't seem to insert the images I snapped, if they would help, I can email them.
3. Since there is no manual for SpeedGrade, I'm about to buy a 3rd party "class in a book" just so I can have some run down of what some of the settings and preferences options actually mean. Like what's "shaders?" Or why does it seem like framerate can be set in three different preference tabs? Would be nice if there was just a document with a run down of settings and preferences for both Premiere and SpeedGrade. Especially since I already have great turorials for the actual operaton of SpeedGrade like Patrick Inhofer's.
Thanks in advance. Wait....do you hear that....Adobe...is that you????
