| Abstract(in English) | Wiener filter is generally used for restoring images polluted by optical blur and gaussian noise. Although Wiener filter estimates the power of Gaussian noise beforehand, a single time-invariant linear filter is used for restoring the entire image so the quality of restored images can be unsatisfactory. We propose the data-dependent Wiener filter that adaptively uses the appropriate filter coefficients at each pixels according to the two different information from the image domain. From the results of our experiments, the proposed method shows excellent results compared with the conventional Wiener filter. |
