In real time applications such as video streaming, it is important that the video encoding/decoding is fast.In video compression technique, most of the complexity comes from the H.264 encoder specifically in the motion estimation (ME) part.Enhanced Predictive Zonal Search (EPZS) is one of the best ME algorithms.In this paper a MATLAB implementation of EPZS algorithm is introduced to provide MATLAB environment for EPZS ME algorithm.The results of the proposed architecture for EPZS were compared with that of full search (FS) motion estimation algorithm for validation.A comparative study between EPZS, FS and the most popular ME algorithms is also performed.The simulation results show that EPZS is better than other fast search algorithms in terms of quality and speed.
