This paper presents a fast motion estimation algorithm by adaptively changing the early termination threshold for the current accumulated partial sum of absolute difference (SAD) value. The simulation results show that the proposed algorithm can provide the similar quality while saving 77.9% and 50.6% of SAD computation when comparing with early termination methods in MPEG-4 VM18.0 and H.264 JM9.0, respectively.
