eCopy and Kofax?

why1525

Dear all,

I am researching Scanning n OCR solution for a company which is using Alfresco now.

There is a question i need to know. Is it any Scanning and OCR software can integrated with Alfrsco easily? or only eCopy and Kofax solution able to do this?

I need this answer very much because the due date is near.

Thanks you.

It doesn't look like you ever got your answer. I'm curious too.

I integrated open source OCR engines Tesseract and Ocropus from Google.

Code is not production ready, but feel free to message me if interested.

Alexander,

I too have played with Tesseract, but with little success. Is it possible for you to pass on some tips?

Hey all.

I spent some time on this finally and have been successful in building and running OCRopus and Tesseract. As per the FAQ: http://code.google.com/p/ocropus/wiki/FrequentlyAskedQuestions OCRopus uses Tesseract as its character recognition plug-in.

All is good running this app from the command line on Ubuntu. Have successfully converted several images of various layouts. (With various results of course!)

I created a Content Transformer through the following file (ocr-transformers-context.xml):

The command ocrocmd ${source} > ${target} works well from the command line (ocrocmd Page1.tif > Page1.html) but falls down when run by Alfresco.

This is a snippet of the trace:

Seems the pipe is being interprected as file to be processed by OCRopus. Placing single quotes around the {} like thus ocrocmd '${source}' > '${target}' doesn't work through Alfresco but does on the command line. The trace from that error is as follows:

I didn't truncate the log, Alfresco (log4j) did. Help! What am I missing? Do I need to escape the pipe? If so, how? I tried just putting a \ in front of it. No go.

Thanks a bunch.

Best,
Ben

I remember making a minor change in Tesseract C source to produce text (not HTML) by default as I did not need HTML and did not want to spend time with figuring out how to pass parameters to command line.

kayseryu

I'm a newbie and I'm just investigating a lil' about all this Alfresco functionality.
About this matter, is there a free OCR working for Windows OS that could work in the same manner that u post before?
Also, I noticed that the transformer class used for tesseract/ocropus is custom made (com.onepoint.transform…) Could you also post the code for this class?

muhammad_qasim

I want the text in the images to be searchable through the search option.
I already installed ocropus and Tesseract. I was searching through the posts until i found this post. I have few questions.
In which folder on Linux should I have to put ocr-transformers-context.xml and what other measures I have to do to enable ocr searching capablities in alfresco. . The system is an Ubuntu 8.x. Alfresco 2.1 is working fine.

Hi,

I found out the web http://www.alfresco-plugin.com or http://www.qdoclive.com on the internet which they have the Scanning Modules with OCR for the Windows. There are some cool features such as

- Zoneing OCR
- OCR/Barcode to Field
- OCR/Barcode to filename/folder name
- Template and Rules supports
- saving to FTP, Webdav, File Sharing supports

Also, compatible with Alfresco 2.1 and 2.9

I think these plugin module is very helpful for the Scanning and Archiving solution, if you are looking to use the Alfresco

Krisapong S.

muhammad_qasim

My logic is…if you are using an open source software then its soulution should also be open source (i mean free).

krisapong

Hello muhammad,

#1 For Full Page OCR you could use Abbyy or Intelliant OCR or others, then you got PDF/a for Searchable PDF. These could allow alfresco do the full text search.

#2 For the aspect creation XML

AspectPath = C:\Alfresco\tomcat\shared\classes\alfresco\\extension\
FileWebConfig = web-client-config-custom.xml
FileCustomModelContext = custom-model-context.xml
AspectFile = <aspectname>Model.xml

Please kindly study at http://wiki.alfresco.com/wiki/Displaying_Custom_Metadata

#3 Create Rule using the previous aspect

#4 Using Alfresco WebService method to send the text to each aspect.
http://wiki.alfresco.com/wiki/Alfresco_Content_Management_Web_Services

#5 Configure the Alfresco Search to search thru these aspect. <using the XML configuration>

I think you need to take a lot of time to study and do it all. that's why the plug-in module will help you. As my opinion, for the enterprise purposed, nothing is free.

Thank you

dranakan

Hello,

I search a software able to convert a TIFF to PDF (txt) and TIFF to TXT working in commandline under Linux and Windows.
I can do that with intelliant, but it doesn't work on Linux (tried with WineHQ).

Somebody knows an OCR working in command line under Linux (ok with Wine) and Windows to transfrom TIFF->PDF and TIFF->TXT (between 50 and 200$) ?

Thanks.

jlabuelo

Hello Dranakan

I have reviewed your post about OCR a tif document to move it to PDF and saw that you got it to work with Intelliant. I am trying to install Intelliant in my Alfresco system (Alfresco 3.0).

Could you please explain me how you got it to work? I have followed the instructions of the user guide of the Alfresco Wiki and Intelliant Tutorial but I dont get it to work.

I have downloaded the Intelliant-Alfresco bundle and installed it in my Windows XP to check if worked fine, but I have two erros:
a) I have configured Alfresco as it is mentioned in the user guide of , but when I launch Alfresco 3 tomcat server and try to go to the log in page, I get the HTTP 404 Resource not available error message.

b) Also if I try to use the Intelliant OCR software using the command line "cmd.exe /k ocr.exe" I get this error message window: "Application does not find MSVCP71.dll. Please try to reinstall again" I have reinstalled the software, but does not work either.

Any help on how I can install Intelliant to make a couple of tests before purchasing the license?

Thanks a lot

dranakan

Hello jlabuelo,

All that I have done was to create a method in Java able to use intelliant. (after my goal was to add it in a custom action). I have not use the connector Intelliant - Alfresco.

Use intelliant-ocr-1.1.exe that you can dowload on (http://intelliant.fr/downloads/intelliant-ocr-1.1.exe).

Try to use it : (put a tif in the directory, use cmd.exe)

ocr.exe file.tif‍

For your library : MSVCP71.dll, I hope that was because you have tried an old version of intelliant… if not, try to add MSVCP71.dll in C:\WINDOWS\system32 (it is just an idea…)

To use in Java code (in Alfresco, after create a custom action using a method that extends ActionExecuterAbstractBase) http://wiki.alfresco.com/wiki/Custom_Actions

//Pass to ocr.exe
Process process = Runtime.getRuntime().exec("ocr " + file);
process.waitFor(); 
….‍‍‍‍

I hope that it can help you…

jlabuelo

Thanks a lot for the answer.. yes I got the comand Intelliant OCR to work now and to produce the expected pdf file.

Now I will take a look to the wiki link about Custom Actions you sent me to see how I can reproduce this in the java code of our customization…. I dont know yet how I will pass the tif node we generate in Alfresco to the Ocr.exe as we dont save it in any place of the C:\ drive, just in the alfresco repository.. and how to get the result and produce a new pdf node with it.

Would you have an example code that you can share with me to use it as a guide?

Thanks a lot again, it has been very usefull.

Regards

HI,

I am using Alfresco Labs Stable in Windows, I downloaded intelliant-ocr-1.1.exe and installed. According to the manual I copied ocr-transformers-context to extension folder. When I restart Alfresco I am getting following error: Error creating bean with name 'transformer.Ocr.Tiff2Pdf' defined in file [C:\Alfresco\tomcat\shared\classes\alfresco\extension\ocr-transformers-context.xml].

Can some please assist

I changed the bean ContentTransformerRegistry of the property explicitTransformations by ExplictTransformationDetails. The bean ExplictTransformationDetails is used by Alfresco in the configuration of other tranformations included in the installation.

I use this code in my configuration and works fine.

Did anyone find an open source solution for making searchable image pdf's? I'm told that gscan2pdf using the tesseract engine can do this, but to port it into Alfresco…?

Hi there,

Does anyone know if intelliant ocr 1.1 is free? Or will it stop working after a set period?

If the latter is the case, are there any ather working open source / free OCR tools to integrate with Alfresco AND able of creating searchable pdfs?

Thanks for any help in advance!

Regards,

Kees.

Hi dranakan, hi all,
i'm trying intelliant ocr but from cmd.exe I get following error:

C:\Programmi\Intelliant OCR>ocr.exe re.tif
OCR progress: page 0/1
Error: Image resolution is inferior to 100 dpi.

Exception of unknown type!

with a following properties image:
Width: 720 pixel
Height: 348 pixel
Oriz resolution: 100 dpi
Vert resolution: 100 dpi

Can you help me to understand that error? I'm newbie

Thanks in advance!

Have a nice weekend

dranakan

Hello Nowhere,

Your image is in 100 dpi. But the error message :

Error: Image resolution is inferior to 100 dpi.‍

Perhaps it's a wrong error message, perhaps the software is not able to process a tiff in 100 dpi or less…

Have you tried wiht a Tif in 200 or 300 dpi ?

Hi dranakan,
thanks for reply.
I did, but I forgot to update this post because I was dealing with another issue (you can read it here http://forums.alfresco.com/en/viewtopic.php?f=9&t=23234 , if you can help).

I tested with a resolution greater then 100dpi and it works. Thanks again for support!

barakobama, Did you get your answers?

I have an extra question. I am dealing with multiple scientific pdf documents in different languages (chinese, russian, german, dutch, english etc)
Would it be possible to scan those with any of the OCR mentioned above? If possible I would like to send the text to a translator api to get an english text back.

Cheers,
Bastiaan

Hello everyone,
I am trying to integrate intelliant with alfresco. It works fine in cmd, but not on Alfresco.
I copied ocr-transformers-context and web-client-config-custom.xml from http://wiki.alfresco.com/wiki/Tiger_OCR_integration to my extension folder. What should I do now with these two files to to have my rule "tif to pdf" working?
Help me, please.

I am afraid that I don't have related experience on such kinds of plug-ins towards Alfresco, however I am interested in the <a style="text-decoration:none;color:#000000" href="http://www.businessrefinery.com/products/barcode_reader_java/main.html">java barcode reader</a> recently, this topic aroused my curiosity and I think I gained a lot from the discussions here.
