中文摘要：
利用连续视频各帧之间的时域和空域相关性,在视频播放超分辨率插值放大重建时,主要对I帧进行边缘检测插值,而对P帧和B帧图像的插值则参考I帧的插值结果,从而提高整个视频播放的主观质量,计算量也不大。实验结果表明,本算法对提高每帧图像以及整体视频主观质量均有明显效果,大大减少了播放时由于视频的放大而出现的块状和锯齿状等失真。
英文摘要：
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.
