On sunday is the 2010 Int. Symp. on Voronoi Diagrams (ISVD). We shall present: Jensen-Bregman Voronoi diagrams and centroidal tessellations Here are the slides of the talk. The Jensen-Bregman divergence is a distortion measure defined by the Jensen difference provided by a strictly

Total Bregman Divergence and its Applications to Shape Retrieval
The following work has been presented at CVPR 2010. It considers orthogonal projection onto a tangent plane instead of vertical projection when defining a distance using a convex generator. Shape database search is ubiquitous in the world of biometric systems,
Simplification and hierarchical representations of mixtures of exponential families
Simplification and hierarchical representations of mixtures of exponential families just got out at Signal Processing Abstract A mixture model in statistics is a powerful framework commonly used to estimate the probability measure function of a random variable. Most algorithms handling mixture models
