随着网络和通信系统的高速发展,交互式计算机和电视技术的普遍应用,以及现代远程教育技术的迫切需要,人们对多媒体数据的编码、解码技术提出了更高的要求。近几年来,视频压缩技术发展迅速,新的视频标准不断推出。MPEG-4是国际运动图像专家组[MPEG]在继MPEG-1和MPEG-2之后,制订的又一个ISO/IEC标准,即ISO/IEC 14496。它能够获得更高的音/视频压缩率,且具有基于内容的交互能力。目前MPEG-4也正在不断的修订,以提出更好的压缩及解压算法,在质量有损最小的前提下,获得更好的压缩效果。本文结合目前视频标准的发展情况,对基于对象的视频编码标准MPEG-4进行了深入的研究,对MPEG-4的编解码结构及视频层次化的数据结构进行了分析,并对编解码的关键技术,如:形状编解码、运动估计和运动补偿以及纹理编解码进行了研究,对其中的核心技术DCT/IDCT变换、逆量化、变长编解码、半像素精度搜索、DC和AC系数的预测等进行了详细的分析。针对MPEG-4 SVP模型,本文介绍了它的解码的详细过程,并结合实际要求,对解码算法进行了优化,给出了解码的软件实现,最后给出了系统的实现情况和测试结果。-无
