Facial expression representation and recognition based on texture augmentation and topographic masking
The variation of facial texture and surface due to the change of expression is an important cue for analyzing and modeling facial expressions. In this paper, we propose a new appr...

On-the-Fly Adaptive Subdivision Terrain
In this paper we present a method to achieve interactive rendering of smooth terrain based on coarse data. Therefore we use adaptive subdivision surfaces which are calculated on t...
