Enhancement - Set OpenCV Image #8

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
For our project we need to combine OpenCV library and tesseract python 
bindings. So it seems more effective to set OpenCV image directly to tesseract 
instead of storing it into a file and let tesseract re-read it. 

Would it be possible to integrate following changes (included in the enclosed 
patch, the diff is made towards revision 95) into the python-tesseract project? 
I tested the patched changes under Ubuntu 11.04.

I also find out that shared tesseract library no longer names tesseract_api, so 
I also edited setup.py.

Thanks for looking on my proposed enhancement! I'm using OpenCV 2.1.0 lib which 
is in the Ubuntu repositories.

Have you linked the _tesseract.so also with the OpenCV lib? I added cv as 
additional library in setup.py script, I thought it is sufficient... Perhaps it 
also needs a cxcore part 
(http://opencv.willowgarage.com/wiki/CompileOpenCVUsingLinux)?

I tried this patch and it works great. Just a note: If you are running OpenCv2, 
all the references to the string "cv.iplimage" need to be changed to 
"cv2.cv.iplimage". But other than that, it works as advertised. Thanks to the 
OP.

I am confused. Why will need to include opencv2? Why not install python-opencv 
instead?

Could you send me simple script on how to use your added functions/methods?

Many thanks

This is an enhancement, not a defect.
