Paper Abstract

In this paper we introduce two novel methods for application of `1-minimization. In the first method, sparse and low-rank decomposition and compressive sensing-based retrieval are combined and applied to a low power surveillance model. The method exploits the ability of sparse and low-rank decompositions to extract significant and stationary features and the ability of compressive sensing approaches to reduce the number of measurements necessary. In the second method, a contiguity prior is added to compressive sensing methods on images and a numerical approach is proposed to solve this novel problem. Results are displayed in which the contiguity constrained method is applied to the low power surveillance model.
