Abstract

A system and method for a low complexity and robust spatiotemporal combining for video enhancement is disclosed. In one embodiment, the method includes computing a standard deviation estimate between a video frame and a temporally neighboring frame of the video frame in a video sequence, computing an error value, for each sub-block of pixels within a block of pixels in a current video frame, between pixel values within the sub-block in the current video frame and corresponding motion compensated pixel values in a temporally neighboring video frame of the current video frame, computing a temporal weighting factor for each sub-block of pixels as a function of the error value and the standard deviation estimate, and combining the block of pixels in the current video frame and their corresponding motion compensated pixel values in the temporally neighboring video frame using the computed temporal weighting factor.
