摘要 可伸缩性视频编码(SVC)技术是图像和视频处理中一个新的研究领域,近年来取得了很多成果。在介绍SVC的有关概念和国内外研究现状的基础上,提出了一种有效的帧速率控制方法。该方法对视频序列建立了图像组(GOP)结构,并给出了对其采用分层运动补偿时间滤波器(MCTF)实现方案以记录帧间的相关性信息。实验结果表明,分层运动补偿时间滤波器结构能提供较高的处理速度和良好的性能,并且能灵活地实现SVC的时间伸缩性。 Scalable video coding(SVC) technology is a new domain in the processing of image and video, and there are many results of SVC at present. This paper introduces the main concept of SVC and brings forward an effective method to control the velocity of the frame. The result of experiments indicates the Motion Compensated Temporal Filter(MCTF) framework can perform higher velocity of processing and better performance, and also neatly achieve the temporal scalability of SVC.
