ABSTRACT:
For decoding, a first portion of an encoded bitstream is decoded to generate a first decoded video frame. A second portion of the encoded bitstream is decoded to generate a second decoded video frame. A temporal filter is applied to the first decoded video frame and the second decoded video frame to generate a filtered second video frame. For encoding, a first unencoded video frame is encoded to generate a first encoded video frame. The first encoded video frame is decoded to generate a first decoded video frame. A second unencoded video frame is encoded to generate a second encoded video frame. The second encoded video frame is decoded to generate a second decoded video frame. A temporal filter is applied to the first decoded video frame and the second decoded video frame to generate a filtered second video frame. A third unencoded video frame is encoded to generate a third encoded video frame. The third encoded video frame is decoded to generate a third decoded video frame, wherein the filtered second video frame is used as a reference frame for generating the third decoded video frame. The temporal filter is applied to the filtered second video frame and the third decoded video frame to generate a filtered third video frame.
