Fast animation and control of nonrigid structures
We describe a fast method for creating physically based animation of non-rigid objects. Rapid simulation of nonrigid behavior is based on global deformations. Constraints are used...

Distance blurring for space-variant image coding
We present a novel selective blurring algorithm that mimics the optical distance blur effects that occur naturally in cameras and eyes. The proposed algorithm provides a realistic...
