I have detected boundaries of an image and I would like to detect the corners for that boundary image(Having boundaries of image).

BW = imread('blobs.png'); [B,L,N] = bwboundaries(BW); figure; imshow(BW); hold on; for k=1:length(B), boundary = B{k}; if(k > N) plot(boundary(:,2),... boundary(:,1),'g','LineWidth',2); else plot(boundary(:,2),... boundary(:,1),'r','LineWidth',2); end end

U can use the corner function to detect the corners.
