Robust Blind Source Separation by Soft Decision-Directed Non-Unitary Joint Diagonalization
Wenjuan Liu, Dazheng Feng, Bingnan Pei +3
Approximate joint diagonalization of a set of matrices provides a powerful framework for numerous statistical signal processing applications. For non-unitary joint diagonalization…
Hyperspectral Image Super-Resolution via Deep Prior Regularization with Parameter Estimation
Xiuheng Wang, Jie Chen, Qi Wei +1
Hyperspectral image (HSI) super-resolution is commonly used to overcome the hardware limitations of existing hyperspectral imaging systems on spatial resolution. It fuses a low-res…
A Fast Algorithm Based on a Sylvester-like Equation for LS Regression with GMRF Prior
Qi Wei, Emilie Chouzenoux, Jean-Yves Tourneret +1
This paper presents a fast approach for penalized least squares (LS) regression problems using a 2D Gaussian Markov random field (GMRF) prior. More precisely, the computation of th…
Robust Fusion of Multi-Band Images with Different Spatial and Spectral Resolutions for Change Detection
Vinicius Ferraris, Nicolas Dobigeon, Qi Wei +1
Archetypal scenarios for change detection generally consider two images acquired through sensors of the same modality. However, in some specific cases such as emergency situations,…
Detecting Changes Between Optical Images of Different Spatial and Spectral Resolutions: a Fusion-Based Approach
Vinicius Ferraris, Nicolas Dobigeon, Qi Wei +1
Change detection is one of the most challenging issues when analyzing remotely sensed images. Comparing several multi-date images acquired through the same kind of sensor is the mo…
Unsupervised Nonlinear Spectral Unmixing based on a Multilinear Mixing Model
Qi Wei, Marcus Chen, Jean-Yves Tourneret +1
In the community of remote sensing, nonlinear mixing models have recently received particular attention in hyperspectral image processing. In this paper, we present a novel nonline…
