Abstract
A method for head pose estimation may include receiving block motion vectors for a frame of video from a block motion estimator, selecting at least one block for analysis, determining an average motion vector for the at least one selected block, combining the average motion vectors over time (all past frames of video) to determine an accumulated average motion vector, estimating the orientation of a user's head in the video frame based on the accumulated average motion vector, and outputting at least one parameter indicative of the estimated orientation.
