Roughly speaking, sparseness-based approaches[21] involve transforming the mixtures into an appropriate representation domain.
The L0-AbS method is based on a simple image model, which has two statistical parameters: α, controlling the amount of sparsity of the sparse approximation of the image in the representation domain, and σ r, which is the standard deviation of the sparse approximation from the actual vector of the image in the representation domain.
The burgeoning field of compressive sampling (CS) addresses the recovery of signals which are sparse either in the original domain or in a different representation domain achieved by a suitable invertible transform.
For easy evaluation of the effectiveness of the proposed approach, signal representation domain D is assumed as an identity matrix IN × N and unknown signal s is set as sparse directly.
The graph-based transform (GBT) has been recently introduced in the framework of video coding [16] to provide a novel representation domain which is able to efficiently capture image discontinuities.
A source is said to be sparse in a given signal representation domain if most of its coefficients, in this domain, are (almost) zero and only a few of them are big.
