摘　　要：近年来小波视频编码技术在快速发展,作为视频编码核心步骤的运动补偿技术更是受到了高度重视.许多用于提高编码效率和提供新功能的观点和方法被提出.在介绍小波视频编码技术特点和基本方法的基础上,着重介绍了运动补偿技术在时域和小波域实现的最新进展,并对发展趋势进行了展望.In last decades, the wavelet-based video codec has been fast developing. As a key role of video eodec the motion compensation has been receiving more and more emphasis. New ideas and new practical designs for high efficiency and powerful functions were prompted out one by one. Based on the introduction of the characteristics and fundamental method of waveletbased video codec, this paper reviews the advances of motion compensation implementation in temporal and wavelet domain, finally the future development is pointed out.
