帧重复方法是最基本的非运动补偿插帧算法。插入帧中每一个像素都是来自于上一帧相同位置的像素,这种算法运算量低、实现难度小,但是对于运动图像来说,图像质量会变差,使得图像抖动或模糊。
,Frame repeat method is the most basic non-motion compensation frame interpolation algorithm. Insert frames from each pixel in the same location as a pixel, th

1) 将y4m格式的视频文件读入到Matlab中,文件可以从如下网站下载:
http://media.xiph.org/video/derf/
2) 使用examples.m将y4m视频文件中的每一帧图像读取出来
3)把奇数帧的偶数行丢弃,把偶数帧的奇数行丢弃,这样就形成了隔行视频
4)分别采用垂直重复,行平均,垂直内插,场平均,行场平均的方法进行去隔行
5)分析结果
