Adaptive Binary Motion Estimation Algorithm for MPEG-4 Shape Coding
Baolong Guo · Yingxiang jishu · 2006
Motion estimation(ME) is a great burden for MPEG-4 shape coding.In this paper,an adaptive binary ME algorithm was proposed.By examining the content of Alpha plane,a binary mask for the effective search area can be generated,the traditional add and plus operation were replaced by 1bit XOR operation,thus lowering the computation complexity.Two search algorithms: SDS and LDS were used for different types of BAB.Experiment results show that the proposed algorithm can reduce the computational complexity of shape coding significantly and be suitable for real-time software and hardware applications.
