A super precision image processing system improves the precision of videos and images and eliminates the stage-like artifacts in the smoothly changing areas. In order to obtain higher precision content, the system segments the input image into connected segments and finds a local support for each pixel based on the segmentation result. The system then applies low-pass filtering to the local support for each pixel and the luminance changes between the filtering result and the original luminance of the pixel are limited to a level such that the output image will have the same higher bits as the input image. |
