摘要: 提出用于可分级视频编码的3带小波提升与运动模型自适应结合的方法,将3带小波的提升步与运动补偿自适应相结合来实现时间域的小波变换,扩展了经典的运动补偿时域滤波,实现了时间分级的灵活性,同时又可以根据实际的视频序列选择适当的运动模型,从而达到更好的编码效果。仿真结果验证了该方法的有效性和性能的优越性。

Abstract: A new method for scalable video coding, using three-band lifting-based motion adaptive transform, is presented in this paper. A three-band motion-compensated lifting steps are used to implement the temporal wavelet transform. It extends the classical Motion-Compensated Temporal Filtering(MCTF) and offers higher temporal scalability flexibility, and it provides improved compression performance by using specific motion model according to real video sequences. The experimental results demonstrate the effectiveness of the framework.

Key words: wavelet transform, lifting, scalable video coding, three-band temporal decomposition, Motion-Compensated Temporal Filtering(MCTF)
