Modified Motion Vector Searches for H.264/AVC

Motion estimation is an important and essential part of video compression. In the encoding process motion estimation is the most computationally intensive part of the encoder. Different search patterns can be used to find the similar blocks between frames. The similarity between the frames is transmitted in the form of motion vectors. In this paper the JM 9.0 software is modified to implement different motion vector searches. This paper shows the effect of the different search patterns on the time taken for motion estimation, the total time taken for the encoding process and bitrate
