The ultimate goal of video compression is to provide best visual quality of the video source by using minimum bit budget. To achieve this target, spatial, temporal and perceptual redundancies should be exploited and removed such that the video source could be compressed efficiently. In this paper, we present how to improve the video compression performance by using a foveated just-noticeable-distortion model. Since the perceptual acuity decreases with the increased eccentricity, a foveation model is developed to exploit the global perceptual redundancy in addition to the spatial and temporal just-noticeable-distortion models. The foveated just-noticeable-distortion model is incorporated into the H.264/AVC video coding system. As demonstrated in the subjective tests, applying the proposed model in video coding can improve visual quality.
