Hello--
So I have a binary image and I only want to remove white from specified areas, such as the corners. (These areas being the circles). How would I do this???
I attached the image.
Regards,

Try thresholding then masking
mask = grayImage > 250; % or whatever intensity the spots are.
grayImage(mask) = 0; % blacken those pixels.
