In Wyner-Ziv video coding, efficient compression is achieved by exploiting source statistics at the decoder only, which is radically different from conventional video coding. The performance of a Wyner-Ziv video codec is greatly dependent on the quality of reconstructed side information, which is an estimation version of current frame. Therefore the correlation between Wyner-Ziv (WZ) frame and key frame implicitly affects the performance of a Wyner-Ziv video codec. In this paper, an adaptive key frame selection method is proposed. Firstly, a simply interest points detector is utilized to detect interest points of a video frame. Then, a kind of interest points based measure, which could represent the correlation between video frames, is performed. If the number of different interest points between two video frames is below a threshold, then it should be transmitted as a key frame, otherwise as a WZ frame. Our experimental results are promising. About 1dB gain in the quality of reconstructed frames has been achieved. |
