I have this binary image. Now I want to crop this image in such a way that I have only the leaf part and the remaining part(which contains another angled black part) are removed. I wont use manual cropping. This should be by final image:

Thank You!

Simply invert then call bwareaopen() and imclearborder()
mask = bwareaopen(~mask, 1000);
mask = imclearborder(mask);
% Invert again if you want black on white (usually that's not a good idea though).
mask = ~mask;
