Something like this

img; % 3D RGB image array
c = []; % list of columns to delete
r = []; % list of rows to delete

img(r,c,:) = []

thanks for you kind response. I didn't get this line of code: img(r,c,:) = []?

[Ameer Hamza]

This line delete the rows specified in vector 'r', and columns specified in vector 'c' from variable img. [] tells MATLAB to delete those lines.
