Abstract:
Described herein is a method and system for the reduction of noise in a video sequence. When motion is present in the video sequence, this system and method identifies motion data. With the motion data, a Motion Compensated Temporal Filter (MCTF) can apply motion compensation prior to filtering in the time domain. Temporal filtering can be performed to reduce visible noise and other detrimental artifacts.
