ABSTRACT:
A method of bidirectional temporal noise reduction in a video signal processing system is provided. A video signal comprising a video sequence of frames is received. Backward temporal noise reduction is performed on the sequence of frames to obtain backward noise-reduced frames. Then, forward temporal noise reduction is performed on the backward noise-reduced frames, to reduce noise in the video sequence of frames.
