Hi,
I am a beginner at image processing in MATLAB and I am asking about examples of how to detect squares in an image.

Are these binary (black and white) or greyscale images?
I'd suggest learning about morphological filters - erode, dilate, open, close, etc.
These spatial operators can be used to find and sort by size squares, rectangles, and other shapes.
Look at imopen and imclose.

There are plenty of examples in the File Exchange:

Don't turn in the code as if it were your own invention though or you could get in trouble with your university.

No one said it would be easy. But I think your professor thinks you're capable enough or else they wouldn't have assigned it to you as homework. Everyone has confidence in you except you.

Sorry,sir. It is my first time to use mathworks and I don't know these things but I really appreciate your effort and time.
