Patent ID: 8160149

Claim:
A computer to improve coding efficiency of video compression of motion compensated moving image frames, the computer comprising: a processor, and a memory, the memory having software code stored therein, the software code when executed by the processor, causes the computer to: reduce the current frame to at least one lower resolution frame using a downsize filter; match pixels of the current frame to pixels of at least one of a previous or subsequent frame to generate a flowfield for the current frame, the flowfield comprising a per-pixel field of motion vectors describing the relative motion of the pixels of the current frame with respect to the pixels of at least one of a previous or subsequent frame and the flowfield being generated by interpolating up motion vectors for the at least one lower resolution frame's flowfield using upsize-filtering to yield one motion vector per pixel; apply the motion vectors of the flowfield for the current frame to modify the current frame by at least one of (1) modulation of at least one resolution-enhancing layer derived from the current frame, (2) sharp/soft filtering for at least one of the current frame, a base layer derived from the current frame, or at least one resolution-enhancing layer derived from the current frame, and (3) displacement of pixels of the current frame; and output the modified current frame.
