Hi Matlab community, I am new to Matlab and sorry if my question is lame. I would like to find the critical points in an image (maxima,minima,saddle points). I am able to find out the maxima and minima using the 'imregionalmax,imregionalmin'function. But i dunno how to find out the saddle points in an image. I really need help, please help me out.
