Adapted generalized lifting schemes for scalable lossless image coding (2008)
Bekkouche, Hocine, Barret, Michel, Oksman, Jacques
Still image coding occasionally uses linear predictive coding together with multi-resolution decompositions, as may be found in several papers. Those related approaches do not take into account all...

The KarhunenLoève Transform (KLT) is optimal for transform coding of Gaussian sources, however, it is not optimal, in general, for non-Gaussian sources. Furthermore, under the high-resolution...

ICA-Based Algorithm Applied to Image Coding (2008)
Narozny, Michel, Barret, Michel
Recently, Narozny et al [1] proposed a new viewpoint in variable high-rate transform coding. They showed that the problem of finding the optimal 1-D linear block transform for a coding system...

Dans cet article nous proposons deux transformations linéaires optimales à faible distorsion pour la réduction de la redondance spectrale en utilisant le codeur EBCOT de JPEG2000, l'une étant...
SCHEMES TO COMPUTE UNSTEADY FLASHING FLOWS Michel Barret (2003)
We provide herein some ways to compute flashing flows in variable cross section ducts, focusing on the Homogeneous Relaxation Model. The basic numerical method relies on a splitting technique which...
Adaptive Multiresolution Decomposition: Application To Lossless Image Compression (2002)
Hocine Bekkouche, Michel Barret
In this paper we introduce the use of adaptive filter banks in lossless compression of images with progressive coding in resolution. During the decomposition the filter adapts itself automatically to...
Adapted Lifting Schemes for Lossless Image Coding (2002)
Hocine Bekkouche, Michel Barret, Jacques Oksman
In this paper we introduce adapted lifting schemes with truncated linear mean square estimation. The idea behind this work is to design subband coders capable of universal performance, in the...
