I did understand that. Let us look at the loop: for (x = 0; x < width; x++) { for (y = 0; y < height; y++) { int positive = (width*height-1); int negative = (y*width+x+kernal_size[filter_scale]/2); ... If the kernal size/2 > 0 then negative *can* get greater than positive for some values of x and y. Everything else are overflow effects. ...or what am I getting wrong here?
