Motion estimation is one of the most demanding and complex tools in block based video
encoders. Variable block size motion estimation (ME) and multiple reference frames in H.
264/AVC make motion estimation even more complex and time consuming. In HEVC, the
complexity is even higher since there are more block sizes. This paper presents an analysis
of various tools involved in some fast ME algorithms and proposes some improvements to
them in order to achieve a novel fast hybrid algorithm. The proposed algorithm has been …
