I am doing a project to read the data on a calculator screen via image processing. I need to make the image binary in such a way that only the digits in the image appear black and the rest is white. Can I do it with any image enhancement tool? Please suggest. Can somebody do it for me?
The link to the image is -
Thanks in advance

use 'histeq' function for enhancement or use 'adapthisteq' by choosing proper clipping range.
After applying this method convert to binary.

See my answer to your duplicate question. I got the numbers out of there using color segmentation and some standard image processing to clean up some noise. I didn't even have to do background correction. You should not accept an answer if it didn't answer your question.
