OCR Plugin

Hi there,

Does anyone knows a nice OCR java library that I may use to add the OCR
feature [1] to the attachment plugin ?

Thanks

I searched for the same some time ago, but didnt come up with anything
useful (free, there seem to be some commercial ones which are ok/
good).
In Open Source world, there is Tesseract possibly (however this is a
binary, and you would have to spawn a process)

Keep me posted about progress in case you find something cool, I need
this for my home paperwork (I never find stuff when I search for in
real life :slight_smile:

Keep in touch

Here is a list from Ubuntu:

When it comes to Java:

The Java project is not very active though...

Here is a good post about OCR analysis
http://stackoverflow.com/questions/971344/java-based-ocr-sdk-api

However, I dont think that OCR in ES side is a good approach, OCRs consume
a lot of resource maybe you will create a bottleneck in ES node. Some of
those OCRs get in deep in embed images, probably will be more expensive for
the machine.

Thanks to all. I think that the best answer is :
http://www.roncemer.com/software-development/java-ocr

FYI, there is one OCR in the cloud : http://ocrsdk.com/plans-and-pricing/
with a Java client : https://github.com/abbyysdk/ocrsdk.com/tree/master/Java

I agree for the bottleneck. Although it could fit to some use cases.
