National audienceWe propose a new Gaussian model to classify high-dimensional data in both supervised and unsupervised frameworks. Our approach is based on the assumption that high-dimensional data live in low-dimensional subspaces. Our model therefore finds the specific subspace and the intrinsic dimension of each class to correctly fit the data. In addition, our approach regularizes the class conditional covariance matrices by assuming that classes are spherical both in their eigenspace and in its supplementary. We thus obtain a robust clustering method for high-dimensional data. Our approach is then applied to recognize object in real images and its performances are compared to classical methods.Nous proposons une nouvelle modélisation g...
