A Fast Motion Estimation Algorithm Scheme Based on Multi-Reference Frame

Abstract

The new H.264 AVC video coding standard supports searching the best motion vector in multi-reference frame, but searching one by one increases calculation complexity. Herein by fully analyzing the affecting factors in multi-reference frame environment, we put forward a new fast motion estimation method base on multiple-reference frame technique. Experiment shows that this could reduce the complexity of motion estimation effectively while retaining high ratio of signal-to-noise and low bit rate.
