Apparatus and method for video data processing

摘要

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.

1. An apparatus for facilitating processing image data of video frames comprising:
a processing component configured to process a reference frame to produce an output frame including:
a first input configured to receive motion vector data for a block of pels of the reference frame that estimates the displacement of the reference frame pels from corresponding pels in a prior input frame; anda second input configured to receive pel data for pels of a prior output frame corresponding to the prior input frame as previously processed; the processing component configured to produce comparison metrics for a reference frame pel of the reference frame block based on a comparison of the reference frame pel and a plurality of neighboring reference frame pels with pels of the prior output frame including:
a first comparison metric based on a comparison with corresponding pels of the prior output frame; anda second comparison metric based on a comparison with corresponding pels of a motion compensated prior output frame derived from applying the motion vector data for the reference frame block to the pels of the prior output frame; and the processing component configured to determine a pel of the output frame that corresponds to the reference frame pel using the first and second comparison metrics; wherein the processing component is configured to use the first comparison metric to determine a first gain for use in blending the reference frame pel with a corresponding pel of the prior output frame to produce a first blended pel and to use the second comparison metric to determine a second gain for use in blending the reference frame pel with a corresponding pel of the motion compensated prior output frame to produce a second blended pel; and wherein the processing component is configured to produce the first and second blended pels and to use the first and second comparison metrics, a motion vector variance value, and a motion vector metric to determine a third gain for use in blending the first and second blended pels to produce a third blended pel upon which the output frame pel corresponding to the reference frame pel is based.
