Hi, I am a new guy of Matlab. Now I need to process one image (see the attachment) which has several small parts, some of them include text, others are not. I want to know how to differ the parts that contain text from the others that do not. In other words, I want to identify the images that include text. Thanks for answers.

This is an algorithm question rather than a MATLAB question.

Thanks Tom. I think I did not make my question clear. What I want to do is to identify the parts that include text in the above image. You can see that there are four small areas in the image. I want a code who tells me that the three areas include text, while the other one (right bottom) does not. Again, thans for your answer.
