运动编码属于MPEG-4校验模型(VM)的关键技术,文中给出一种基本的运动编码算法实现流程,同时改进有形状VO运动检测中阈值的计算方法,以及在实现了无限运动估计,高级预测,重复填充技术和多边形匹配等技术的基础上对不同匹配准则和搜索算法进行了测试比较,并给出实验结果,从而来更加优化快速的实现MPEG-4基于对象的运动编码和解码。
Motion coding belongs to the key technology of MPEG-4 verification model (VM). In this paper, we present a flow of basic motion coding algorithm and improve the threshold calculation method of shape-based V0 motion detection. At the same time, Advanced prediction, refill technology and polygon matching techniques based on the different matching criteria and search algorithms were tested and compared to give the experimental results, in order to more optimal and rapid implementation of MPEG-4 object-based motion encoding and decoding.
