I wish to set the value of a pixel at a certain coordinate to zero in an image. Any idea how to do this? The coordinate is (641,513) (the middle).
Thanks in advance,
JB

I = imread(img);
I(614,513)=0;

x is column, y is row. So I(x,y) is not the same location as I(row, column). If you want x = 20, y = 100, you need to do I(100, 20), not I(20,100) because the row (the y value) index comes first. This is a common source of confusion and errors and you need to always watch out for this.
