Gradually Atom Pruning for Sparse Reconstruction and Extension to Correlated Sparsity
Smoothed l0 l1 minimization compressed sensing reconstruction algorithm correlated sparsity

We propose a new algorithm for recovery of sparse signals from their compressively sensed samples. The proposed algorithm benefits from the strategy of gradual movement to estimate the positions of no...

Abstract: A major challenge in sparsity pattern estimation is that small modes are difficult to detect in the presence of noise. This problem is alleviated if one can observe samples from multiple rea...
