The richness of natural images makes the quest for optimal representations in image processing and computer vision challenging. The latter observation has not prevented the design of image representations, which trade off between efficiency and complexity, while achieving accurate rendering of smooth regions as well as reproducing faithful contours and textures. The most recent ones, proposed in t...<br/><br/>Laurent Jacques, Laurent Duval, Caroline Chaux, Gabriel Peyré (2011) <i>Signal Processing</i> 91: 12 2699-2730<br/>

An important issue with oversampled FIR analysis filter banks (FBs) is to determine inverse synthesis FBs, when they exist. Given any complex oversampled FIR analysis FB, we first provide an algorithm to determine whether there exists an inverse FIR synthesis system. We also provide a method to ensure the Hermitian symmetry property on the synthesis side, which is serviceable to processing real-va...<br/><br/>Jérôme Gauthier, Laurent Duval, Jean-Christophe Pesquet (2009) <i>IEEE Transactions on Signal Processing</i> 57: 10 3827-3843<br/>

The use of multicomponent images has become widespread with the improvement of multisensor systems having increased spatial and spectral resolutions. However, the observed images are often corrupted by an additive Gaussian noise. In this paper, we are interested in multichannel image denoising based on a multiscale representation of the images. A multivariate statistical approach is adopted to tak...<br/><br/>C Chaux, L Duval, A Benazza-Benyahia, J C Pesquet (2008) <i>IEEE TRANSACTIONS ON SIGNAL PROCESSING</i> 56: 8 3855-3870<br/>

Comprehensive two-dimensional gas chromatography (GCxGC) is a major advance for the detailed characterisation of petroleum products. This technique is based on two orthogonal dimensions of separation achieved by two chromatographic capillary columns of different chemistries and selectivities. High-frequency sampling between the two columns is achieved by a modulator, ensuring that the whole sample...<br/><br/>C Vendeuvre, R Ruiz-Guerrero, F Bertoncini, L Duval, D Thiebaut (2007) <i>OIL & GAS SCIENCE AND TECHNOLOGY-REVUE DE L INSTITUT FRANCAIS DU PETROLE</i> 62: 1 43-55<br/>

Dual-tree wavelet decompositions have recently gained much popularity, mainly due to their ability to provide an accurate directional analysis of images combined with a reduced redundancy. When the decomposition of a random process is performed-which occurs in particular when an additive noise is corrupting the signal to be analyzed-it is useful to characterize the statistical properties of the du...<br/><br/>C Chaux, J C Pesquet, L Duval (2007) <i>IEEE TRANSACTIONS ON INFORMATION THEORY</i> 53: 4680-4700<br/>

We propose a two-dimensional generalization to the M-band case of the dual-tree decomposition structure (initially proposed by Kingsbury and further investigated by Selesnick) based on a Hilbert pair of wavelets. We particularly address: 1) the construction of the dual basis and 2) the resulting directional analysis. We also revisit the necessary pre-processing stage in the M-band case.

The detailed characterisation of middle distillates is essential for a better understanding of reactions involved in refining process. Owing to higher resolution power and enhanced sensitivity, comprehensive two-dimensional gas chromatography (GC x GC) is a powerful tool for improving characterisation of petroleum samples. The aim of this paper is to compare GC x GC and various ASTM methods - gas ...<br/><br/>C Vendeuvre, R Ruiz-Guerrero, F Bertoncini, L Duval, D Thiebaut, M C Hennion (2005) <i>JOURNAL OF CHROMATOGRAPHY A</i> 1086: 1-2 21-28<br/>

Seismic exploration provides information about the ground substructures. Seismic images are generally corrupted by several noise sources. Hence, efficient denoising procedures are required to improve the detection of essential geological information. Wavelet bases provide sparse representation for a wide class of signals and images. This property makes them good candidates for efficient filtering ...<br/><br/>L Duval, C Chaux (2004) <i>International Journal of Wavelets, Multiresolution and Information Processing (IJWMIP) </i> 2: 4 455-476<br/>

Comprehensive two-dimensional gas chromatography (GC x GC) has been investigated for the characterization of high valuable petrochemical samples from dehydrogenation of n-paraffins, Fischer-Tropsch and oligomerization processes. GC x GC separations, performed using a dual-jets CO2 modulator, were optimized using a test mixture representative of the hydrocarbons found in petrochemicals.
