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.

Artifact removal method and system for contoured images and video

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.
