Starting from a link with the discrete polynomial decomposition, we propose an extension of the non-uniform filter bank framework to vector-valued signals to carry out a non marginal color wavelet transform. Recently quaternions or Clifford algebras

International audience; Image decomposition into structures and texture components appears as major objectives in image analysis. Following to Yves Meyer works that are based on Total Variation (VT), the decomposition model has been a renewed interes

International audience; In this paper, we propose a new polynomial based texture representation method for extracting information about facial expressions. While many appearance-based methods have been proposed over the years to improve the performan

We introduce a new analysis tool able to test the learning distribution inside an MLP network. This tool is based on the exploitation of specific indicators which measure the contribution of any interconnection graph subset to the information gain ev

We describe a reconstruction method of three dimensional marker trajectories from several cameras in the applicative framework of sportive gesture analysis. The principle is to apply a tracking algorithm on extracted markers from each sequence of ima
