We present a catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), during the first 11…
The curvelet transform for image denoising
- Jean-Luc Starck, E. Candès, D. Donoho
- Computer ScienceProceedings International Conference on Image…
- 7 October 2001
In the tests reported here, simple thresholding of the curvelet coefficients is very competitive with 'state of the art' techniques based on wavelets, including thresholded of decimated or undecimated wavelet transforms and also including tree-based Bayesian posterior mean methods.
Sparse Solution of Underdetermined Systems of Linear Equations by Stagewise Orthogonal Matching Pursuit
- D. Donoho, Y. Tsaig, Iddo Drori, Jean-Luc Starck
- Computer ScienceIEEE Transactions on Information Theory
- 1 February 2012
Stagewise Orthogonal Matching Pursuit (StOMP) successively transforms the signal into a negligible residual, and numerical examples showing that StOMP rapidly and reliably finds sparse solutions in compressed sensing, decoding of error-correcting codes, and overcomplete representation are given.
Image decomposition via the combination of sparse representations and a variational approach
- Jean-Luc Starck, Michael Elad, D. Donoho
- Computer ScienceIEEE Transactions on Image Processing
- 1 October 2005
A novel method for separating images into texture and piecewise smooth (cartoon) parts, exploiting both the variational and the sparsity mechanisms is presented, combining the basis pursuit denoising (BPDN) algorithm and the total-variation (TV) regularization scheme.
THE FERMI-LAT HIGH-LATITUDE SURVEY: SOURCE COUNT DISTRIBUTIONS AND THE ORIGIN OF THE EXTRAGALACTIC DIFFUSE BACKGROUND
- A. Abdo, M. Ackermann, M. Ziegler
- Physics
- 1 September 2010
This is the first of a series of papers aimed at characterizing the populations detected in the high-latitude sky of the Fermi-LAT survey. In this work, we focus on the intrinsic spectral and flux…
The Undecimated Wavelet Decomposition and its Reconstruction
- Jean-Luc Starck, M. Fadili, F. Murtagh
- GeologyIEEE Transactions on Image Processing
- 1 February 2007
New filter banks specially designed for undecimated wavelet decompositions which have some useful properties such as being robust to ringing artifacts which appear generally in wavelet-based denoising methods are presented.
Image Processing and Data Analysis - The Multiscale Approach
- Jean-Luc Starck, F. Murtagh, A. Bijaoui
- Computer Science
- 1 July 1998
The wavelet transform is used for multiscale vision models, and its applications in remote sensing, 3D signal processing, and variation stabilisation are also studied.
Wavelets, Ridgelets, and Curvelets for Poisson Noise Removal
- B. Zhang, M. Fadili, Jean-Luc Starck
- MathematicsIEEE Transactions on Image Processing
- 1 July 2008
A variance stabilizing transform (VST) is applied on a filtered discrete Poisson process, yielding a near Gaussian process with asymptotic constant variance, leading to multiscale VSTs (MS-VSTs) and nonlinear decomposition schemes.
