Bayesian anti-sparse coding
Clément Elvira, Pierre Chainais, Nicolas Dobigeon
Sparse representations have proven their efficiency in solving a wide class of inverse problems encountered in signal and image processing. Conversely, enforcing the information to…
Online Unmixing of Multitemporal Hyperspectral Images accounting for Spectral Variability
Pierre-Antoine Thouvenin, Nicolas Dobigeon, Jean-Yves Tourneret
Hyperspectral unmixing is aimed at identifying the reference spectral signatures composing an hyperspectral image and their relative abundance fractions in each pixel. In practice,…
Fast Single Image Super-Resolution
Ningning Zhao, Qi Wei, Adrian Basarab +3
This paper addresses the problem of single image super-resolution (SR), which consists of recovering a high resolution image from its blurred, decimated and noisy version. The exis…
Fast Spectral Unmixing based on Dykstra's Alternating Projection
Qi Wei, Jose Bioucas-Dias, Nicolas Dobigeon +1
This paper presents a fast spectral unmixing algorithm based on Dykstra's alternating projection. The proposed algorithm formulates the fully constrained least squares optimization…
Hyperspectral pansharpening: a review
Laetitia Loncan, Luis B. Almeida, José M. Bioucas-Dias +12
Pansharpening aims at fusing a panchromatic image with a multispectral one, to generate an image with the high spatial resolution of the former and the high spectral resolution of…
Combining local regularity estimation and total variation optimization for scale-free texture segmentation
Nelly Pustelnik, Herwig Wendt, Patrice Abry +1
Texture segmentation constitutes a standard image processing task, crucial to many applications. The present contribution focuses on the particular subset of scale-free textures an…
