Using an average motion vector for a motion search

Abstract:

A method for using an average motion vector in a motion vector search process. The method includes accessing an input frame for processing and reading average motion vector information from memory. The method further includes performing a motion vector search by using the average motion vector and a plurality of hints, calculating a winner motion vector based on the average motion vector and the plurality of hints, and storing the winner motion vector back into memory to create a new updated average motion vector. The method further includes finishing processing the input frame using the winning motion vector.
