Abstract. In this paper, we first present a video quality metric based on human vision. We then propose a new perceptual video local activity metric. These two metrics are of great interest for the optimizatiion of both the transmission and the coding of video sequences. Consequently, next we motivate the use of these metrics in order to increase the end-user perceptual quality of MPEG-2 based video services by showing results on three different application fields.
