OCR and Extract

Hi,
I have two questions:
1) When I try to "Recognize Text Using OCR" a document (which is a collection of scanned images of invoices), the result is extremely poor, with most of characters not being recognized at all. The image quality is not great, but I have been able to obtain better results by a) printing an invoice and scanning it with OCR; and b) using Able2Extract from www.ocr.com. However, a) would take too long and b) doesn't seem to have the option of saving OCRed pages as PDF.
My question is: is it possible to OCR a lower quality PDF more reliably in Acrobat. If not, is there another software that can do this?
2) Is it possible to extract pages that satisfy certain conditions? For example, can you extract all pages that contain any kind of notes or markings (e.g. Acrobat highlights) or pages that contain certain words?
Thanks in advance your assistance.

An answer to question 2 is a conditional yes. The condition is that you have a version which is not Reader (which I assume you do), and also you will need a custom-made script that will determine which pages to extract. Contact me by email if you're interested in such a tool.

Ocr and voting file heth

Hi gurus,
is there any method to check health of the ocr and voting files. How do we know that if ocr or voting files are corrupted.
Thank you!

Want to crop an image of car and extract number plate from it.

i have a problem in my project.I have to crop the edges of a car's image and i want to extract only it's number plate.The OCR i am using can not extract charcters which are skewed etc.Can i have a code through which i can crop an image and extract only specific part?

Is this a college project ?
Cos it sounds extremely tricky to attempt.
If I was attempting this I might
1. Assume a fixed camera position.
So that I'd know what the road looked like without any cars.
Take a photo of this road as a "control background".
2. Assume a standard number plate system.
In Ireland, they've a white background, black lettering.
No italic writing.
Then, when I detect a car ( say more than 5% of the "control background" is covered ), I might try searching for the black & white lettering.
This might involve scanning the image from left to right, top to bottom, and defining rectangular ranges of black & white pixels.
( I'd allow multiple regions, so there could be more than 1 plate in the photo.
It might even pick up sign-writing on vans and cars ! )
That's just my initial quick idea of how to attempt it.
Could be easier ways...

Owen

I need help. My ipad 2 was stuck in recovery mode. i tried to connect it to itunes and restore but after downloading the file and extracting the software there is a pop up message that says "the device is full" i dont know what to do. Its been 2 days now.

I need help. My ipad 2 was stuck in recovery mode. i tried to connect it to itunes and restore but after downloading the file and extracting the software there is a pop up message that says "the device is full. Deleting files and emptying your recycle been will help you restore." how am i going to erase files if i can't open my ipad. i dont know what to do. Its been 2 days now. please help. thanks.

yes i am sure. This are the exact words... "The iPad "iPad" could not be restored. The disk you are attempting to use is full. (Removing files and emptying the recycle bin will free up additional space". i tried some options, hard reset, redsnow, tinyumbrella but still it's stuck.

How can I read the bootstrap files and extract the fragment-URLs and fragment-numbers in plain text?

How can I read the bootstrap files of any HDS Live stream and extract the fragment-URLs and fragment-numbers in plain text?
Could it be that it is some kind of compressed format in the bootstrap? Can I uncompress it wirh f4fpackager.exe? Could not find any download for f4fpackager.exe. I would prefere less code to do so. Is there something in Java of JavaScript, that can extract the fragment-numbers?
Thank you!

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

Front end Backend Modeling Configuration Reporting and Extraction.

Hi..All
Can Any one plz explain the terms "Front end","Back end" related to Modeling,Configuration,Reporting and Extraction.
Thanks & Regards
Jonn
<u>[email protected]</u>

Hi,
Frontend is the reporting aspect, i.e Workbooks, queries, Web reporting, Crystal reports, etc.
Its called the frontend as that's what the users see and they don't see what goes on in the 'backend' i.e Config and Extraction, data manipulations, etc.
Modeling is used to design the cube, ODS, etc. Also modeling concepts can be used to design frontend queries as well.

OCR and voting disks on ASM, problems in case of fail-over instances

Hi everybody
in case at your site you :
- have an 11.2 fail-over cluster using Grid Infrastructure (CRS, OCR, voting disks),
where you have yourself created additional CRS resources to handle single-node db instances,
their listener, their disks and so on (which are started only on one node at a time,
can fail from that node and restart to another);
- have put OCR and voting disks into an ASM diskgroup (as strongly suggested by Oracle);
then you might have problems (as we had) because you might:
- reach max number of diskgroups handled by an ASM instance (63 only, above which you get ORA-15068);
- experiment delays (especially in case of multipath), find fake CRS resources, etc.
whenever you dismount disks from one node and mount to another;
So (if both conditions are true) you might be interested in this story,
then please keep reading on for the boring details.
One step backward (I'll try to keep it simple).
Oracle Grid Infrastructure is mainly used by RAC db instances,
which means that any db you create usually has one instance started on each node,
and all instances access read / write the same disks from each node.
So, ASM instance on each node will mount diskgroups in Shared Mode,
because the same diskgroups are mounted also by other ASM instances on the other nodes.
ASM instances have a spfile parameter CLUSTER_DATABASE=true (and this parameter implies
that every diskgroup is mounted in Shared Mode, among other things).
In this context, it is quite obvious that Oracle strongly recommends to put OCR and voting disks
inside ASM: this (usually called CRS_DATA) will become diskgroup number 1
and ASM instances will mount it before CRS starts.
Then, additional diskgroup will be added by users, for DATA, REDO, FRA etc of each RAC db,
and will be mounted later when a RAC db instance starts on the specific node.
In case of fail-over cluster, where instances are not RAC type and there is
only one instance running (on one of the nodes) at any time for each db, it is different.
All diskgroups of db instances don't need to be mounted in Shared Mode,
because they are used by one instance only at a time
(on the contrary, they should be mounted in Exclusive Mode).
Yet, if you follow Oracle advice and put OCR and voting inside ASM, then:
- at installation OUI will start ASM instance on each node with CLUSTER_DATABASE=true;
- the first diskgroup, which contains OCR and votings, will be mounted Shared Mode;
- all other diskgroups, used by each db instance, will be mounted Shared Mode, too,
even if you'll take care that they'll be mounted by one ASM instance at a time.
At our site, for our three-nodes cluster, this fact has two consequences.
One conseguence is that we hit ORA-15068 limit (max 63 diskgroups) earlier than expected:
- none ot the instances on this cluster are Production (only Test, Dev, etc);
- we planned to have usually 10 instances on each node, each of them with 3 diskgroups (DATA, REDO, FRA),
so 30 diskgroups each node, for a total of 90 diskgroups (30 instances) on the cluster;
- in case one node failed, surviving two should get resources of the failing node,
in the worst case: one node with 60 diskgroups (20 instances), the other one with 30 diskgroups (10 instances)
- in case two nodes failed, the only node survived should not be able to mount additional diskgroups
(because of limit of max 63 diskgroup mounted by an ASM instance), so all other would remain unmounted
and their db instances stopped (they are not Production instances);
But it didn't worked, since ASM has parameter CLUSTER_DATABASE=true, so you cannot mount 90 diskgroups,
you can mount 62 globally (once a diskgroup is mounted on one node, it is given a number between 2 and 63,
and other diskgroups mounted on other nodes cannot reuse that number).
So as a matter of fact we can mount only 21 diskgroups (about 7 instances) on each node.
The second conseguence is that, every time our CRS handmade scripts dismount diskgroups
from one node and mount it to another, there are delays in the range of seconds (especially with multipath).
Also we found inside CRS log that, whenever we mounted diskgroups (on one node only), then
behind the scenes were created on the fly additional fake resources
of type ora*.dg, maybe to accomodate the fact that on other nodes those diskgroups were left unmounted
(once again, instances are single-node here, and not RAC type).
That's all.
Did anyone go into similar problems?
We opened a SR to Oracle asking about what options do we have here, and we are disappointed by their answer.
Regards
Oscar

Hi Klaas-Jan
- best practises require that also online redolog files are in a separate diskgroup, in case of ASM logical corruption (we are a little bit paranoid): in case DATA dg gets corrupted, you can restore Full backup plus Archived RedoLog plus Online Redolog (otherwise you will stop at the latest Archived).
So we have 3 diskgroups for each db instance: DATA, REDO, FRA.
- in case of fail-over cluster (active-passive), Oracle provide some templates of CRS scripts (in $CRS_HOME/crs/crs/public) that you edit and change at your will, also you might create additionale scripts in case of additional resources you might need (Oracle Agents, backups agent, file systems, monitoring tools, etc)
About our problem, the only solution is to move OCR and voting disks from ASM and change pfile af all ASM instance (parameter CLUSTER_DATABASE from true to false ).
Oracle aswers were a litlle bit odd:
- first they told us to use Grid Standalone (without CRS, OCR, voting at all), but we told them that we needed a Fail-over solution
- then they told us to use RAC Single Node, which actually has some better features, in csae of planned fail-over it might be able to migreate
client sessions without causing a reconnect (for SELECTs only, not in case of a running transaction), but we already have a few fail-over cluster, we cannot change them all
So we plan to move OCR and voting disks into block devices (we think that the other solution, which needs a Shared File System, will take longer).
Thanks Marko for pointing us to OCFS2 pros / cons.
We asked Oracle a confirmation that it supported, they said yes but it is discouraged (and also, doesn't work with OUI nor ASMCA).
Anyway that's the simplest approach, this is a non-Prod cluster, we'll start here and if everthing is fine, after a while we'll do it also on Prod ones.

How to examine pdf for image file formats, OCR, and layers

Hi,
I have a question about how to find out specific features of a pdf. I am using Adobe Acrobat 9 Pro for windows.
With any given PDF, I am looking to find out:
a] The specs of any image files used to create the pdf (i.e., if the pdf is made up of text pages with image objects on top of them, are those image objects JPGs? TIFFS? What resolution are they? Are they compressed?)
b] Does this PDF have OCR already embedded in it?
c] Does this PDF have multiple layers?
with a] -- file format is perhaps the most important, resolution and compression being second most
with c] -- is there an easy way to see the layers, visually, on the page images?
What is a smiple way to find out this information?
I've poked around a bit in the "Examine Document" function, and various checks in "Preflight," as well as the help manual, and have found bits and pieces that look like some of what I'm looking for, but nothing simple or conclusive yet.
Any help or advice would be wonderful! I just want a simple way to be able to see what my PDF is made out of, in terms of image files, OCR, and layers.
Thanks,
Andrew

Preflight is inded the best way to do this operation. You may have to read a bit to figure out what you are looking at, but that is the right route to take.

How do I define 2 disk groups for ocr and voting disks at the oracle grid infrastructure installation window

Hello,
It may sound too easy to someone but I need to ask it anyway.
I am in the middle of building Oracle RAC 11.2.0.3 on Linux. I have 2 storage and I created three LUNs in each of storage so 6 LUNs in total look in both of servers. If I choose NORMAL as a redundancy level, is it right to choose my 6 disks those are created for OCR_VOTE at the grid installation? Or should I choose only 3 of them and configure mirroring at latter stage?
The reason why I am asking this is that I didn't find any place to create asm disk group for ocr and voting disks at the oracle grid infrastructure installation window. In fact, I would to like to create two disk groups in which one of groups contains three disks those were brought from storage 1 and the second one contains rest three 3 disk that come from the last storage.
I believe that you will understand the manner and help me on choosing proper way.
Thank you.

Hi,
You have 2 Storage H/W.
You will need to configure a Quorum ASMDisk to store a Voting Disk.
Because if you lose 1/2 or more of all of your voting disks, then nodes get evicted from the cluster, or nodes kick themselves out of the cluster.
You must have the odd number of voting disk (i.e 1,3 or 5) one voting disk per ASM DISK, So 1 Storage will hold more voting disk than another storage.
(e.g 3 Voting Disk - 2 voting stored in stg-A and 1 voting disk store in stg-B)
If fail the storage that hold the major number of Voting disk the whole cluster (all nodes) goes down. Does not matter if you have a other storage online.
It will happen:

Api for OCR and reading .pdf and .doc(x) files

Hi Guys,
Happy new year to you all!
I am trying to write an app that will read the text in an image, a .pdf or .doc(x) file and extract some information from it. I want this app to be a universal windows app. Is there an api for performing these actions?
Thanks and God bless.
The best things in life are free, but the most valuable ones are costly...use opportunities well for there are others like you who deserves them, but don't have them...

No built-in APIs, but I am sure there are third-party APIs for this.

How to browse a file and extract its contents

i want to browse a file and extract its contents.My code is given below but its not working .Can anybody help me please
JFileChooser fc = new JFileChooser();

          if (returnVal == JFileChooser.APPROVE_OPTION)
          File file = fc.getSelectedFile();
          //This is where a real application would open the file.
          fileName=file.getName();
          //This is a file function to extract data from a file.

// append text to a StringBuffer (variable named sb here) or directly in a textarea.

Unable to select and extract object...

I am currently attempting to edit a recently converted raster to vector image. I have the file opened and selected after having used the "live trace" function to revise it and save as a vector image. Now I would like to select and extract a portion of the image to work with but I am neither able to select and extract the object of focus from within the general picture. When I attempt to use the pointer selection tool to select the object of focus, the entire image becomes selected with a blue border. If I try to use the magic wand nothing happens. If I try to use the lasso tool I can draw around the object of focus but when I close the lasso it simply disappears leaving nothing selected. I've even tried to "ungroup" the image but option is grayed out (unavailable). Any insights into what I am doing incorrectly? By the way, the live trace function becomes active whenever I click anywhere within the general image.

RUConscious,
Expanding the Live Trace should make it accessible and editable just like any other vector artwork where you may Direct Select individual/multiple Anchor Points, Select paths, etc.
Maybe a closeup of the issue area, with a hint at what exactly you wish to do, would help the helpers, preferably including the relevant part of the Layers panel (which may be moved).
Apart from that, others may tell you that I am too old, or silly, to apply Live Trace.

File Read and Extract

Hi,
I have a script which runs and generates log files. Rather than manually read through these log files, I'd like to code a program which will take the file, read through it and extract the data I wish to extract.
For example, it may read:
bla bla bla
bla bla bla
23/03/05 - 151105 Files
bla bla bla
23/03/05 - Elapsed Time: 3m 50s
bla bla bla
24/03/05 - 51250981502 files
bla bla
24/03/05 - Elapsed Time: 59m 12s
bla bla
etc etc.
So I want to ignore the "bla bla bla", pick out my keywords, such as file, time and print out the number next to it, preferably to a nice little html file or something :)
I am able to read files and I think I can pick out keywords using string tokenizers, although this is more advanced than tokenizers I've used before. I used a buffer to split the file and read it line by line.
I'm pretty stumped, although this seemed like a straight forward thing to do at the time....
Any advice to get me going?
Thanks!

you could use a reg ex to match on xx/xx/xx and still read line by line.
or you could use Integer.parseInt and always parse the first two characters of a line, if they parse they are integers, but maybe blah has integers in the first two positions as well.

Confusion with OCFS2 File system for OCR and Voting disk RHEL 5, Oracle11g,

Dear all,
I am in the process of installing Oracle 11g 3 Node RAC database
The environment on which i have to do this implementation is as follows:
Oracle 11g.
Red Hat Linux 5 x86
Oracle Clusterware
ASM
EMC Storage
250 Gb of Storage drive.
SAN
As of now i am in the process of installing Oracle Clusterware on the 3 nodes.
I have performed these tasks for the cluster installs.
1. Configure Kernel Parameters
2. Configure User Limits
3. Modify the /etc/pam.d/login file
4. Configure Operating System Users and Groups for Oracle Clusterware
5. Configure Oracle Clusterware Owner Environment
6. Install CVUQDISK rpm package
7. Configure the Hosts file
8. Verify the Network Setup
9. Configure the SSH on all Cluster Nodes (User Equivalence)
9. Enable the SSH on all Cluster Nodes (User Equivalence)
10. Install Oracle Cluster File System (OCFS2)
11.Verify the Installation of Oracle Cluster File System (OCFS2)
12. Configure the OCFS2 (/etc/ocfs2/cluster.conf)
13. Configure the O2CB Cluster Stack for OCFS2
BUT, here after i am a little bit confused on how to proceed further. The next step is to Format the disk and mount the OCFS2, Create Software Directories... so and so forth.
I asked my system admin to provide me two partitions so that i could format them with OCFS2 file system.
He wrote back to me saying.
*"Is what you want before I do it??*
*/dev/emcpowera1 is 3GB and formatted OCFS2.*
*/dev/emcpowera2 is 3GB and formatted OCFS2.*
*Are those big enough for you? If not, I can re-size and re-format them*
*before I mount them on the servers.*
*the SAN is shared storage. /dev/emcpowera is one of three LUNs on*
*the shared storage, and it's 214GB. Right now there are only two*
*partitions on it- the ones I listed below. I can repartition the LUN any*
*way you want it.*
*Where do you want these mounted at:*
*/dev/emcpowera1*
*/dev/emcpowera2*
*I was thinking if this mounting techique would work like so:*
*emcpowera1: /u01/shared_config/OCR_config*
*emcpowera2: /u01/shared_config/voting_disk*
*Let me know how you'd like them mounted."*
Please recommend me what i should convey to him so that i can ask him to the exact same thing.
My second question is, as we are using ASM, for which i am gonna configure ASM after clusterware installation, should i install Openfiler??
Pls refer the enviroment information i provided above and make recommendations.
As of now i am using Jeffery Hunters guide to install the entire setup. You think the entire install guide goes well with my enviroment??

Thanks for ur reply Mufalani,
You have managed to solve half part of my query. But still i am stuck with what kind of mount point i should ask the system admin to create for OCR and Voting disk. Should i go with the mount point he is mentioning??
Let me put forth few more questions here.
1. Is 280 MB ok for OCR and voting disks respectively??
2. Should i ask the system admin to create 4 voting disk mount points and two for ocr??
3. As mentioned by the system admin.
*/u01/shared_config/OCR_config*
*/u01/shared_config/voting_disk*
Is this ok for creating the ocr and voting disks?
4. Can i use OCFS2 file system for formating the disk instead of using them as RAW device!!?
5. As u mentioned that Openfiler is not needed for Configuring ASM... Could you provide me the links which will guide me to create partition disks, voting disks and ocr disks!! I could not locate them on the doc or else were. I did find a couple of them, but was unable to identify a suitable one for my envoirement.

About OCR and Vote Disk size

Hallo,
I have a simple question about OCR and Vote Disk in a 10g/11g RAC setup:
official documentation speaks about sizing OCR and Vote Disk about 280 MB, but do they mean each OCR and Vote disk LUN ?
In other words, for 2 OCR and 3 Vote disk I need 280*5 MB ( in multiple o single LUN)
Is it so?
thx in advance
