Title: Adaptive super-resolution image restoration based on regularization in spatial domain
Abstract: Aiming at the restoration of blurred image,an effective approach to super-resolution image restoration is proposed based on regularization technique for dealing with ill-posed problem.Under the frame of the regularized super-resolution restoration which is pro-posed by Nguyen.Regularization item is choosen which based on the Roberts cross gradient operator and determines the regularization parameter adaptively.The conjugate gradient method is used to solve the minimum of the constraint equation.Computer simulations show that this proposed approach can properly retrieve the main information of original image,and the RE(relative error),the PSNR(peak signal to noise ratio) and subjective effect of the restored image are improved significantly.
