Abstract
Scalable coding techniques usually focus on enhancing the quality of the whole frame when more bandwidth is available. However, not all regions in a frame are equally important to user perception. This paper proposed a user-oriented approach to facilitate scalable coding in spatial and temporal domains. By combining user attention and foveation models, the regions of user's focus in a frame (spatial domain) or the segment of a video clip with steady saliency values (temporal domain) are prioritized as far as perceived quality is concerned.
