摘要
目前基于压缩感知的视频编解码器在对视频帧图像进行处理时大多采用固定分组的形式,视频中出现场景快速变化时,其重构视频帧的效果较差。提出一种基于压缩感知的自适应帧图像分组视频编解码器,无论场景变化快慢,均能获到较好的视频帧重构效果。实验结果表明,视频场景快速变换时该编解码器的视频帧重构效果较好。
Currently, ,most video eodec based on compressive sensing using a fixed grouping mode for the video frame image. When the video scene rap- idly changing,its reconstructed video frame effect is poor. In this paper,a adaptive frame image grouping video codec based on compressive sensing is proposed. Whether fast or slow scene changes,good quality of reconstructed video frames are obtained. Simulation results show that our scheme is better in reconstructed video frame quality compared with the fixed grouping mode in the rapidly changing video scenes.
