An Improved Output-Size Sensitive Parallel Algorithm for Hidden-Surface Removal for Terrains
We describe an efficient parallel algorithm for hiddensurface removal for terrain maps. The algorithm runs in Olog4 n steps on the CREW PRAM model with a work bound of On + kpolyl...

Hash-Based Motion Modeling in Wyner-Ziv Video Coding
Generally, Distributed video coding (DVC) schemes perform motion estimation at the decoder side, without the current frame being available. In order to generate the side-informati...

An improved distortion model for rate control of DCT-based video coding
This paper presents a rate control algorithm for the dominant discrete cosine transform (DCT) -based video coding. It is developed based on a more accurate rate-distortion (RD) mo...

Incremental sparse saliency detection
By the guidance of attention, human visual system is able to locate objects of interest in complex scene. We propose a new visual saliency detection model for both image and video...

Tracking of human activities using shape-encoded particle propagation
We present an approach to tracking human activities in a monocular video. We model the human body by decomposing it into torso and limbs and use simple 3D shapes to approximate th...
