I am doing a project on Optical character recognition. After reading the bmp file header, we binarize the image. Why do we need to binarize? can we proceed without binarizing? is there any other method?

Solution 1

Because binary image is sufficient for OCR. Algorithm needs to recognize characters, they can be represented with one color and there is background which can be represented with second color. This also makes algorithm fast because it has less data to deal with.
