I want to determine the rectangles and circles in the picture with different colors and write numbers on them. For example, I want to see how many circles and how many rectangles there are, can you please help with the code?

  • binarize image
  • use imfindcircles
I0 = imread('img1.jpeg');
I1 = im2bw(I0);
[cc,rr] = imfindcircles(~I1,[50 100]);
imshow(I1)
viscircles(cc,rr)
