- W623557007 abstract "Restoration of the blurry and noisy digital images is a very active research area in image processing. The deconvo- lution, in the presence of noise, is well known to be an ill-posed problem. This paper introduces a novel approach composed of two optimized sequential steps of processing: noise reduction followed by deconvolution. In the first step, the denoising filter and the number of iteration are chosen in order to obtain the best value of the usual criteria and the good recovering of the blurry image. We assume that the statistics of the noise are previously estimated. In the second step, a deconvolution method is applied on an almost noise free version of the blurry image. Compared with the classical deconvolution methods, the numerical experiments of the proposed method, appear to give significant improvement. The preliminary results for the new cascade approach are very encouraging as well." @default.
