Image deblurring was formulated as an optimization problem regularized by l_p norm.A fast generalized iterative shrinkage thresholding algorithm(FGISA)was proposed to solve it.The FGISA algorithm accelerated the generalized iterative shrinkage thresholding algorithm(GISA)by multiplying a weighting matrix to the gradient function of the GISA together with the well-known Nesterov's strategy.Since the weighting matrix was only predetermined by the blur kernel and fixed,therefore,comparing with GISA,FGISA did n...
