Detection, location, and processing of static pixels

摘要

Systems and methods may provide for the detection, location, and processing of static pixels during video processing. In one example, the method may include determining if a color component value of a pixel located at a pixel location remains constant between a first frame and a next frame, determining if the pixel is a low-difference pixel, calculating a motion-compensation error of the color component, determining if the motion compensation error of the color component is large, and generating a map of static pixels including the pixel.

1. A system, comprising:
a processing component; a difference value module to determine if a color component value of a pixel located at a pixel location remains constant between a first frame and a next frame by calculating a difference value of the color component; a low-difference value module to determine if the pixel is a low-difference pixel by determining if the difference value of the color component is lower than a threshold value; a motion compensation comparison module to determine if a motion compensation error of the color component is large by comparing the motion compensation error of the color component with an error threshold of the color component, and an overwriting module to prevent the pixel from being overwritten by preventing a non-static pixel with an incorrect motion vector from being compensated to a static pixel location.
