Abstract:
A system and method that reduce or eliminate step-contouring generated by compression algorithms are provided because many types of compression algorithms introduce a step-contoured artifact for images and video with slow gradients. The system and method restores the gradient to a piece of content by detecting a start and end of the step contour in each row and column of the piece of content and increments a pixel in certain regions of the row or the column to restore the gradient in the piece of content.
