Sparse Approximation of Images Inspired from the Functional Architecture of the Primary Visual Areas

EURASIP Journal on Advances in Signal Processing, Vol 2007 (2007)
Several drawbacks of critically sampled wavelets can be solved by overcomplete multiresolution transforms and sparse approximation algorithms. Facing the difficulty to optimize such nonorthogonal and nonlinear transforms, we implement a sparse approx

Tensor voting (TV) methods have been developed in a series of papers by Medioni and coworkers during the last years. The method has been proved efficient for feature extraction and grouping and has been applied successfully in a diversity of applicat

Maternal insulin and insulin-like growth factors (IGFs) promote development and growth of preimplantation embryos. They regulate differentiation-specific gene expression and balance embryonic energy and glucose metabolism. Changes in maternal metabol

A step index multimode optical fiber with a perturbation on a micrometer scale, inducing a periodic deformation of the fiber section along its propagation axis, is theoretically investigated. The studied microperturbation is mechanically achieved usi

Optical Sensing and Detection.
We present a new kind of intrinsic intensity modulation optical fiber sensor. The sensitive effect is obtained by a mechanical perturbation of the fiber at the micrometric scale. The fiber diameter and the refractive indices are locally modified. The

Today, multiresolution (MR) transforms are a widespread tool for image fusion. They decorrelate the image into several scaled and oriented sub-bands, which are usually averaged over a certain neighborhood (window) to obtain a measure of saliency. Fir

We present a scheme for image fusion based on a 2D implementation of the Wigner Distribution (WD) combined with a multisize windows technique. The joint space-frequency distribution provided by the WD can be managed as a measure of saliency that indi

Orthogonal and biorthogonal wavelets became very popular image processing tools but exhibit major drawbacks, namely a poor resolution in orientation and the lack of translation invariance due to aliasing between subbands. Alternative multiresolution

Gabor representations present a number of interesting properties despite the fact that the basis functions are nonorthogonal and provide an overcomplete representation or a nonexact reconstruction. Overcompleteness involves an expansion of the number
