Paper Abstract

A novel redundant dictionary of sparse representation is proposed to detect infrared small targets. Redundant dictionary plays an important role in sparse representation, and is the key point to guarantee the sparseness of solution. Different from traditional intensity dictionary, in this letter, the gradient information and retinal sampling pattern are used to construct the novel redundant dictionary, in which pixels near the centre have higher sampling density. It can effectively reduce the influence of background clutter around target. Consequently, it is easy to discriminate target from background according to the sparsity of the representation coefficient vector. Experimental results demonstrate that the presented method is robust and efficient.
