Good morning to everyone
I have an 600 x 400 Gray image, The center of course is the pixel of coordinates [600/2 , 400/2], how can i have the coordinates starting in this pixels ( in other word, the central pixel will be with [0 , 0] coordinates like an axis) ??
Thank you

dx=-300;
dy=-200;
imshow(I,'Xdata',[1 size(I,1)]+dx,'Ydata',[1 size(I,2)]+dy)

alternatively you can use surf()
