Quality evaluation method considering time transition of coded video quality

We propose the new quality evaluation method of coded video which is considering the time transition of video quality. The evaluated quality value is computed as the weighted mean of the frame quality by using the weighted function which is derived from the short-term characteristic of human memory. In this case, the time transition of video quality is obtained from the series of the frame quality of whole frame. The optimal weighted function for each coded video is found by using the Genetic Algorithm. The obtained video quality has a good agreement with MOS.
