Abstract
A video processing method comprising receiving a video stream comprising a plurality of frames, removing via one or more non-binary artifact functions a plurality of artifact pixels from the video stream, and outputting the video stream with the artifact pixels removed.
Claims9
A video processing method comprising the steps of:
- receiving a video stream comprising a plurality of frames;
- generating from the video stream a motion-compensated video stream via a mask indicating where motion compensation is valid, wherein the mask is generated by evaluating compensated blocks to find the largest squared difference between two pixels and dividing by a maximum value found in either block subtracted from a minimum value in either block;
- removing via one or more non-binary artifact functions a plurality of artifact pixels from the motion-compensated video stream;
- and
- outputting the motion-compensated video stream with the artifact pixels removed.
