Abstract
A system and method that reduce or eliminate the compression artifact of step-contouring in a piece of content having a gradient are provided because many types of compression algorithms introduce a step-contoured artifact for images and video with slow gradients. An artifact removal unit detects the start and end of a step contour, determines a gradient of the step contour and increments a pixel in certain regions to restore the gradient.
