Abstract EN
This paper addresses the image restoration problem which remains a significant field of image processing.
The fields of experts- (FoE-) based image restoration has been discussed and some open issues including noise estimation and parameter selection have been approached.
The stochastic method FoE performs fairly well; meanwhile it might also produce unsatisfactory outcome especially when the noise is grave.
To improve the final performance, we introduce the integration with deterministic method K-SVD.
The FoE-treated image has been used to obtain the dictionary, and with the help of sparse and redundant representation over trained dictionary, the K-SVD algorithm can dramatically solve the problem, even though the pretreated result is of poor quality under severe noise condition.
The experimental results via our proposed method are demonstrated and compared in detail.
Meanwhile the test results from both qualitative and quantitative aspects are given, which present the better performance over current state-of-art related restoration algorithms.
