I'm using tesseract 3.0.2, seems like it cannot read text with very bright background (see image). Is there a way to do so? Microsoft Azure works better and can read the text.

Simple thresholding should work. You'll have to use something like OpenCV or your own routine if you are daring. If you convert to gray, anything less than 64 (out of 255) goes to black, and anything above that goes to white.

Will it still recognize black/white text if thresholding?
