We propose the use of attentional cascades based on the DCT and motion information contained in an MPEG coded stream. An attentional cascade is a sequence of very efficient class...
MPEG-4 Advanced Simple Profile video provides I, P, and B –type frames in each GOP (Group Of Pictures). To maximize the coding efficiency, it is important to determine the distr...
This paper aims at improving perceptual quality of encoded video sequences, and proposes a new perceptual bit allocation scheme for H.264. Firstly, a new motion complexity measure...
In this paper we present multimedia adaptation strategies for live video streams, at the streaming server, where we switch among several versions of the coded multimedia to match ...
