Abstract:

A recovery algorithm, named generalized semi-iterative hard thresholding pursuit, was proposed. The algorithm modifies the searching direction of objective function with semi-iterative idea, has a polynomial acceleration convergence, and can be used for the signal without sparse information. It is shown that the proposed algorithm did improve the performance in term of reconstruction probability, peak signal-to-noise ratio, signal-to-noise ratio, and matching rate. The reconstruction quality in ghost imaging with the proposed algorithm is superior to that with the generalized hard thresholding method.
