Abstract:
Current output pictures of video data are generated utilizing a motion compensated (MC) blended picture and a corresponding non-MC blended picture of the video data. Windows of picture data from a first picture and MC windows of picture data from a MC previously output picture may be partitioned. The partitioned widows are compared and the first picture is blended with the MC previously output picture based on the comparison to, for example, reduce noise and prevent motion trail artifacts. Non-MC windows of picture data from a MC or non-MC previously output picture may be partitioned and compared with the windows of picture data from the first picture. The first picture may be blended with the MC or non-MC previously output picture based on the comparison to reduce motion trail artifacts. A blending factor is determined and utilized to blend the blended pictures to reduce noise and prevent motion artifacts.
