I have attached a quick sample of what I mean. I used opencv and defer greatly to the blog post I reference at the top of the script, but the idea would be to try to catch single characters using opencv’s “inrange” function. I would use tesseract on the image first and weed out blobs for further processing based on the coordinates of what tesseract has already detected. I would then use single character mode on what’s left. Feel free to ping me if you are interested in this approach. Thanks for your suggestion! Looks like a neat way to circumvent the problem. However, I'd prefer to find the reason why tesseract rejects those blobs first. (See my other post.) Maybe this can be fixed in tesseract, once I know some background... :-) Cheers, --leo -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
