| Abstract(in English) | Most of the image restoration filters proposed so far include parameters which control the characteristics of the filters. For obtaining fine restoration images, values of the parameters should be determined appropriately. In this paper, we propose a method for optimizing the parameters by using the model selection criterion called the subspace information criterion (SIC). SIC is an estimate of the mean squared error between restoration image and unknown original image, and it agrees with the expected mean squared error over the noise for any linear filters. We apply SIC to the moving-average filter, and derive an analytic form of the optimal parameter value. Finally, the effectiveness of the proposed method is demonstrated through computer simulations. |
