Face recognition using mixtures of principal components
We introduce an efficient statistical modeling technique called Mixture of Principal Components (MPC). This model is a linear extension to the traditional Principal Component Anal...

Orthonormal Finite Ridgelet Transform for Image Compression
A finite implementation of the ridgelet transform is presented. The transform is invertible, non-redundant and achieved via fast algorithms. Furthermore we show that this transfor...

Model-Based Estimation of Facial Expression Parameters from Image Sequences
In this paper we present a model-based algorithm for the estimation of 3D motion and the analysis of facial expressions of a speaking person. A set of facial animation parameters ...

A New Color Filter Array With Optimal Sensing Properties
We propose a new color filter array (CFA) with optimal characteristics for the acquisition of color scenes, since the luminance and chrominance information is encoded in the mosai...
