Hi, I have to write a code that only considers what is within a certain pattern of circles in a black and white image. To do this, I overlayed an image of a bracket of circles outlined in black over the picture that I want to analyze, and now I only want to get data about the parts of the picture that are within the circles. (Specifically, I want to count the number of black pixels vs white pixels within all the circles). Please let me know if there is a way to disregard the parts of the picture that are not outlined by the circles.
Thank you!

If you have a binary mask of the circles, you can just do
numBlack = nnz( circles & ~BW );
numWhite = nnz( circles & BW);
