I have a problem with the current tesseract. I have documents that have sections of varying background and text colors. Ive read that tesseract v3 was white/black invariant and it didn't matter if I had white text on red background. But now it matters. The problem is, other parts in the same image are black text on white background. Tesseract 4 fails to identify the white text on red background at all.
I have tried inverting the image colors so red (0xFF0000) becomes cyan (0x00FFFF) and the white text (0xFFFFFF) becomes black (0x000000). I then take the highest confidence text for the region. This improves some scenarios, but for the red/white scenario, does not work. Questions: 1. How can I extract the text to be black and the background to be white, before using tesseract? 2. Is there a way to configure tesseract to "just work"? I've been trying to figure out how to do this for some time, and I haven't made any progress. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
