Finding peak value in 2d array (image)
I'm new to Matlab... I need to find the peak value stored in a 2d array which is actually an image (640x480). I need to know the row,column, and pixel value of the peak. Ideally I'd like something along the lines of [r,c,p] = findPeak(I). I've been stumbling around trying to find a solution to what I know is probab... 23 Nov 2009 15:13
