Sparsity-based Cholesky Factorization and its Application to Hyperspectral Anomaly Detection
Ahmad W. Bitar, Jean-Philippe Ovarlez, Loong-Fah Cheong
Estimating large covariance matrices has been a longstanding important problem in many applications and has attracted increased attention over several decades. This paper deals wit…
Sparse and Low-Rank Matrix Decomposition for Automatic Target Detection in Hyperspectral Imagery
Ahmad W. Bitar, Loong-Fah Cheong, Jean-Philippe Ovarlez
Given a target prior information, our goal is to propose a method for automatically separating targets of interests from the background in hyperspectral imagery. More precisely, we…
Robust Model Order Selection in Large Dimensional Elliptically Symmetric Noise
Eugénie Terreaux, Jean-Philippe Ovarlez, Frédéric Pascal
This paper deals with model order selection in context of correlated noise. More precisely, one considers sources embedded in an additive Complex Elliptically Symmetric (CES) noise…
