Abstract
Embodiments include a video data encoding method comprising receiving video input frames, and performing motion estimation on the video received frames. The motion estimation comprises performing a hierarchical motion search to find motion vectors with optimum sum of absolute difference (SAD) values, and performing spatial filtering of the motion vectors, wherein spatial filtering comprises making some pairs of motion vectors the same to achieve a zero differential.
