Joint Segmentation and Deconvolution of Ultrasound Images Using a Hierarchical Bayesian Model based on Generalized Gaussian Priors
Ningning Zhao, Adrian Basarab, Denis Kouame +1
This paper proposes a joint segmentation and deconvolution Bayesian method for medical ultrasound (US) images. Contrary to piecewise homogeneous images, US images exhibit heavy cha…
Proceedings of the second "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'14)
L. Jacques, C. De Vleeschouwer, Y. Boursier +64
The implicit objective of the biennial "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) is to foster collaboration between interna…
Bayesian estimation of the multifractality parameter for image texture using a Whittle approximation
Sébastien Combrexelle, Herwig Wendt, Nicolas Dobigeon +3
Texture characterization is a central element in many image processing applications. Multifractal analysis is a useful signal and image processing tool, yet, the accurate estimatio…
Hyperspectral and Multispectral Image Fusion based on a Sparse Representation
Qi Wei, José Bioucas-Dias, Nicolas Dobigeon +1
This paper presents a variational based approach to fusing hyperspectral and multispectral images. The fusion process is formulated as an inverse problem whose solution is the targ…
Unsupervised Unmixing of Hyperspectral Images Accounting for Endmember Variability
Abderrahim Halimi, Nicolas Dobigeon, Jean-Yves Tourneret
This paper presents an unsupervised Bayesian algorithm for hyperspectral image unmixing accounting for endmember variability. The pixels are modeled by a linear combination of endm…
A Hamiltonian Monte Carlo Method for Non-Smooth Energy Sampling
Lotfi Chaari, Jean-Yves Tourneret, Caroline Chaux +1
Efficient sampling from high-dimensional distributions is a challenging issue which is encountered in many large data recovery problems involving Markov chain Monte Carlo schemes.…
