[tesseract-ocr] Need help improving text recognition in scanned documents

We are using ImageMagic and tesseract to try to read information in documents, but we are not finding the right configuration and combination of both softwares to optimize the original scanned tif document, and apply tesseract to it to obtain the information. First we use to scan the documen

Hello, I've trained tesseract with only this characters: 0123456789-. I used one tiff with this characters, with 6 samples of each. After the successfully training, tesseract only recognize if in the input tiff there are more than 3 numbers. With a tiff with, for example this numbers 65 it retur

On what device are you going to use it? I tried using it in an IPhone 3gs and it was taking 3 minutes to process a picture! Is that normal? -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group. To post to this group, send email to tesseract-ocr@googl

Re: Customising Tesseract for character recognition

modify the source code. As I just modified a function I could go back to normal and implement that outside the tesseract framework. thank you very much for the help! regards, jose -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group. To post

I fire the execution of the tesseract in the command line and I didn't find a way to format the results with more info. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group. To post to this group, send email to tesseract-ocr@googlegroups.com. To unsu

Re: Customising Tesseract for character recognition

yes, I got the information from the result! I only modify has the result method prints the result.. nothing more of course! I got the information from the bounding box of the result! I'm not modifying it deeper than that. -- You received this message because you are subscribed to the Google Group

Re: Customising Tesseract for character recognition

the results and I can now that x1 and x2 where in the same line due looking at the top value. the approach works fine to me but I had to modify the sourcecode of tesseract regards, jose -- You received this message because you are subscribed to the Google Groups "tesseract-ocr&q

Re: Customising Tesseract for character recognition

Dmitry the recognition works the only thing is the way it is parsing it... :S I think segmentation of the images would be too much painful! I only won't to change the other that is display or the bounding boxes so I could now the x and y of the word recognized and thereby can organise the results b

Re: Customising Tesseract for character recognition

Hi, (as you now Saurabh because we talked in private the other day) I tried the PSM_SINGLE_COLUMN and the accuracy drops dramatically... I can't afford to loose that accuracy. Is it possible to change the way the output is display? Looking a the code it seems rather hard to change it... perhaps I c

Re: Customising Tesseract for character recognition

Saurabh by setting on this: PSM_AUTO,PSM_SINGLE_BLOCK, PSM_CHAR are you forcing the page to read horizontally? My problem is that I have a column of two words separated by a white space (each word is in a diferent font) and Instead of seeing one column of two words the OCR sees two columns of one w

Re: Customising Tesseract for character recognition

ok I'll try that! I have to modify this on the tesseractmain.cpp right? (I'm using command line execution) I replace this line : api.SetPageSegMode(tesseract::PSM_AUTO); for api.SetPageSegMode(tesseract::PSM_SINGLE_COLUMN); and then recompile right? thanks for the help -- You received this mess

Re: Customising Tesseract for character recognition

Is there no other workarround? If I reduce the white space size of the WORD1 WORD2 then it all works fine! This space is making the OCR think it's another column! Is there no another way? Splitting the image as many rows looks something not really eficient -- You received this message because you
