Global motion vector calculation using phase plane correlation

摘要

A method of performing motion compensation includes dividing at least one frame of image data into blocks, performing phase plane correlation to determine a correlation surface for each block between a first frame and a second frame, using the correlation surfaces for each block in the first frame to produce a global correlation surface for a first frame, using the global correlation surface to produce a refined correlation surface, selecting peaks in the refined correlation surface, and perform sub-pixel motion vector calculations to produce global motion vectors using the peaks.
