Abstract: Methods and apparatus for facilitating processing a reference frame to produce an output frame. Motion vector data for a block of reference frame pels estimates the displacement of the reference frame pels from corresponding pels in a prior input frame. Comparison metrics are produced for a pel of the reference frame with respect to that pel and a plurality of neighboring reference frame pels. A first comparison metric is based on a comparison with corresponding pels of a prior output frame that corresponds to the prior input frame as previously processed. A second comparison metric is based on a comparison with corresponding pels of a motion compensated prior output frame derived from applying motion vector data to the pels of the prior output frame. A pel of the output frame that corresponds to the reference frame pel is determined using the first and second comparison metrics.
