Rate-distortion bounds for motion compensated rate scalable video coders
In this paper, we derive and evaluate theoretical ratedistortion performance bounds for scalable video compression algorithms which use a single motion-compensated prediction (MCP...

Segmentation of non-rigid video objects using long term temporal consistency
This paper presents a new object-based segmentation technique which exploits a large temporal context in order to get coherent and robust segmentation results. The segmentation pr...

Region-based active contours for video object segmentation with camera compensation
In this paper, we present a new algorithm for the segmentation of moving objects in a video sequence acquired by a mobile camera using region-based active contours. Indeed, active...

A temporal error concealment method for MPEG coded video using a multi-frame boundary matching algorithm
Compressed video sequences are very sensitive to channel disturbances when they are transmitted through an unreliable environment such as a wireless channel. The transmission erro...
