The image compression standard JPEG 2000 offers a high compression ef ciency as well as a great exibility in the way it accesses the content in terms of spatial location, quality ...
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...
Sprite-based video coding offers higher compression efficiency than conventional block-based hybrid video coders. In sprite coding a sequence is divided into a model of its backgr...
Abstract. Video plus depth based 3D video gradually goes mobile. Taking into account the time-varying characteristics of wireless communication, this paper proposes a multi-pass va...
