Nov 25, 2008 · I recently ran an experiment to look at different OCR (using Adobe Acrobat Pro) fonts to help us Airgap code, which OCR is notoriously bad at handling. I found that you can just about guarantee 100% success if the code/text is converted to Hex, and if Book Antiqua with a size 14 font (full results are below) is used.

Nov 13, 2012 · For that purpose, I am converting its pages to pictures and adding them back to a PDF file. The main issue is that any OCR program can get back the whole written text, especially that the page is going to be clear (as opposed to a scanned book) which will increase the OCR accuracy. So, is there a font that can't be recognized by an OCR.

If you want to train tesseract with the new font, then generate .traineddata file with your desired font. For generating .traineddata, first you will need .tiff file and .box file. You can create these files using jTessBoxEditor. Tutorial for jBossTextEditor is here. While making .tiff file you can set the font in which you have train tesseract.

Jan 5, 2017 · I have to recognize text from Image, which is possible because there are a lot of library found of OCR, but now I have to find the text size and font type also. I have searched a lot but got no help, this is possible, there is an application "WhatTheFont" available on store which is finding the font type that is best match.

I am interested in using OCR to extract bold and italic words from a simple text. For example, if I input a clear image with text like so: "The quick brown fox jumps over the lazy dog." I would l...

Sep 2, 2010 · If an OCR engine can read your font in the first place then I would just use it and not worry about it. There are better options to pick to improve recognition. Many OCR engines allow you to set some recognition parameters to help improve recognition such as fixed width or proportional, serif or non-serif, machine or hand print.

Dec 31, 2015 · I want to use Tesseract to recognize a single noiseless character with a typical font (ex. Times New Roman, Arial, etc. No weird font). The input image just contains the character, so the input image size is equivalent to the font size.

Jul 14, 2015 · My experience is, that tesseract has problems distinguishing the "Z" and the "2" due to the changed similarity of the other font-designs. Therefore I think I can achieve better recognition results if only one font-type (for example Arial) is …

Feb 9, 2011 · I'm trying to use tesseract-OCR via python-tesseract to read a low resolution font that looks like this: Unfortunately that image returns . ZIJZHZI I think the resolution is too low and that is causing problems. I've tried magnifying the image, and cropping it down to individual characters, but neither of these provide much improvement.

Dec 22, 2014 · The issue isn't the font size as much as it is with the letters connecting. If you zoom in on the above images with a program that will show the actual pixels (rather than blurring them together) you can see that those grouping two characters are actually connected. tessearctOCR is completely based on connected components so if they are connected at all then it throws it completely off.
