There is an entropyfilt() function in the Image Processing Toolbox.
rgbImage=imread('ban.jpeg');subplot(121),imshow(rgbImage);grayImage=rgb2gray(rgbImage);[segment,blackSpots]=bwlabel(~im2bw(grayImage,0.7)); % Choose the threshold as per requirements
total_bk_spots=blackSpots-1%................^ minus 1 for ignoring largest blobbs
subplot(122),imshow(segment);
If not, then do the color thresholding.
