Low Rank and Group-Average Sparsity Driven Convex Optimization for Direct Exoplanets Imaging

Abstract: Direct exoplanets imaging is a challenging task for two main reasons. First, the host star is several order of magnitude brighter than exoplanets. Second, the great distance between us and the star system makes the exoplanets-star angular dis- tance very small.
