Abstract
A video encoder includes a motion search module that determines a motion search motion vector for a region of a selected picture of the plurality of pictures. The motion search module determines the region by merging selected ones of a plurality of blocks of the selected picture based on an evaluation of a cost matrix associated with the plurality of blocks of the selected picture.
Claims14
A video encoder for use in a video processing device that processes a video signal including a sequence of pictures, the video encoder comprising:
- a motion search module, that determines a motion search motion vector for a region of a selected picture of the sequence of pictures, wherein the motion search module determines the region by merging selected ones of a plurality of blocks of the selected picture based on an evaluation of at least one cost matrix associated with the plurality of blocks of the selected picture wherein the evaluation includes determining when a first cost matrix of a first block of the plurality of blocks lacks a dominant minimum by identifying a minimum entry of the first cost matrix and comparing the minimum entry to a threshold.
A method for use in a video encoder that encodes a video signal including a sequence of pictures, the method comprising:
- determining a motion search motion vector for a region of a selected picture of the sequence of pictures by merging selected ones of a plurality of blocks of the selected picture based on an evaluation of at least one cost matrix associated with the plurality of blocks of the selected picture wherein the evaluation includes determining when a first cost matrix of a first block of the plurality of blocks lacks a dominant minimum by identifying a minimum entry of the first cost matrix and comparing the minimum entry to a threshold.
