Abstract

Recently, many researches on frame skipping are conducted to reduce temporal redundancy in video frames. As a simple method, fixed frame skipping (FFS) adjusts frame rate by skipping frame at regular intervals. To overcome the poor performance of FFS, variable frame skipping (VFS) has been introduced to exploit the temporal dependency between frames. In this paper, scene-adaptive key frame selection method with low complexity is proposed. The proposed method performed about 20 percent better in complexity with the better visual quality than the conventional video encoding. As a preprocessing method, the proposed technology can be used with any conventional video codec.
