How can I create a loop that will create multiple ellipses on this image? I would like to do this so that I can calculate the mean RGB values of each ellipse. Here is the code I have so far.

img = imread('peppers.png'); h_im = imshow(img); e = imellipse(gca,[220 90 30 30]); BW = createMask(e,h_im); BW(:,:,2) = BW; BW(:,:,3) = BW(:,:,1); ROI = img; ROI(BW == 0) = 0; figure, imshow(ROI);
