Et Aveugles En Traitement Du Signal Et Des Images

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...

Ondelettes et applications en imagerie et en calcul de surfaces

This thesis is a theorical and numerical contribution to wavelet transform in image processing and surface computing. Group theory approach, multiresolution approach and lters banc approach of wavelets basis are reviewed. The wavelet transform applications concern image compression, discrete curve representation and surface approximation by radial functions. We begin by reviewing di erent image...

Indicateurs en biologie et en imagerie au sein des systèmes d'information de santé

Introduction: Health information system (HIS) has been widely studied in order to evaluate their effectiveness. However the results are heterogeneous and the methods are rarely adapted to the french health system. This work aims at developing a tool for HIS description and listing indicators frequently used to assess its benefits in the fields of laboratory and radiology. Those tools will allow...
