A new rate-minimizing matching criterion and a fast algorithm for block motion estimation
We present a new block matching criterion for motion estimation in video coding that will give better encoded video quality than the commonly used sum of absolute differences (SAD...

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...
