Thank you very much for your interest.

But this solution seems complicated to me or difficult for me to understand .

Is there an easier solution than this by Morphology and logical operations like (imerode ,imdilate,imclose

,imopen ..... ) and the output is a number of squares objects only ?

Thank you again for your interest.

Depends on how robust you want to be. The method many/most people use is to find the centroid, then find the boundary, then find the distance from the centroid to each boundary point. Then call findpeaks() to count the number of peaks. So that's not too difficult to understand. One of my demos does it that way.

Did you try to adapt it to use your image instead of the synthetically generated shapes that I created in the demo? If not, why not? Just delete the part where I create the shapes and replace it with a call to imread().
