I am doing this
Write a MATLAB function which computes the 2D joint histogram, GXY ,
of a pair of images, X and Y, of equal size. Test it on the red and green
components of the Queen Butterfly image.
Display the joint histogram, GXY , as a grey level image.
here is my attempt:
for k = 1:size(row)
it's not working at all . Thanks in advance for help in edit the code.
