Method and system for motion compensated picture rate up-conversion of digital video using picture boundary processing

摘要

Certain aspects of a method and system for motion-compensated picture rate up-conversion (PRUC) of digital video using picture boundary processing may include generating one or more forward motion vectors and one or more backward motion vectors based on extracted picture rate up-conversion (PRUC) data. A cost of performing motion estimation of a particular block along the generated forward motion vectors and the generated backward motion vectors corresponding to the particular block may be calculated. The particular block may be a boundary block. A motion vector with the least cost may be selected and motion compensated to generate a plurality of interpolated pictures.

1. A method for processing video data, the method comprising:
determining to perform motion compensated interpolation between two adjacent pictures based on a generated motion vector consistency value between the two adjacent pictures, wherein the motion vector consistency value is generated by comparing adjacent block motion vectors and motion-compensated block boundary pixel differences; responsive to the determination, performing bi-directional motion estimation on a pixel block position by forward and back projecting a motion vector onto at least the two adjacent pictures to generate a forward motion vector and a backward motion vector; selecting a motion vector having a lesser cost measurement for the pixel block between the forward motion vector and the backward motion vector; and generating an interpolated picture comprising the pixel block based on the motion vector selected.
