tesseract shifts UZN coordinates for OCR

[Philcat]

I am able to create a UZN file from rectangle coordinates drawn around text.

Example (pretend the blue background is a rectangle):

Unwanted text.

This is the text I want    

It could be an address   

Mr. Smith                       

10 Fake Street               

Fake Town                      

Phone: 123456 54545    

Email: sm...@email.com

More unwanted text.

The result I get will be something like:

Unwanted text.

This is the text I want    

It could be an address   

Mr. Smith                       

10 Fake Street               

Fake Town    

This would be the same for each line in the UZN file. How do I fix this without manually adjusting the UZN coordinates for each text box?

Thanks.

Provide testing case (image + uzn) + details about version of tesseract language data.

Your uzn file is wrong. Did you tried to visualize?  

If I tried attached uzn file (tesseract Load.tiff - --psm 4) I got this result:

Which mean if you create correct uzn file you will get what you need...

Hey thanks a lot for your help! 

FYI I get the uzn from a QT rubberband/rectangle.

It looks like your results are what I want but the visualization is wrong.

For me the visualization is correct but the results are wrong.

Anyway, you put me on the right track.

Thanks again.

[Philcat]

By the way, what application are you using to visualize the UZN?

Thanks

Very nice! You make it look easy.

Maybe I can use it to see why Qt mouse positions are different to what tesseract reads.

Thanks!
