Playing-video superresolution enlargement algorithm based on reference frames
基于参考帧的视频播放超分辨率放大算法*

This paper reconstructed and enlarged the playing-video of superresolution interpolation by utilizing the temporal and spatial correlations among the frames of continuous video. Firstly, author mainly detected the edge of I-frame and interpo- late. Then ,for P-frame and B-frame, the interpolation was based on the result of the interpolation of the I-frame. Therefor this algorithm could improve the interpolated playing-video subjective quality and the computation strength of the proposed algo- rithm was acceptable. The simulation results show that the algorithm has evident effect on improving the subjective quality of both every frame image and the entire video, and the block and serration distortion are also reduced largely when video is played enlargedly.
