Various methods and apparatuses for motion estimation

摘要

Various methods, apparatuses, and systems are described to determine motion estimation. An image processing engine may have a full search motion estimation engine that matches blocks of pixel data from a first video frame to a second video frame in a raster order to determine the motion estimation. The image processing engine may further include a post processing stage to implement a search pattern algorithm on blocks of pixel data in a search window, where the search pattern starts and proceeds outward from a central region of the search window.
