Abstract
A restoration filter called the averaged projection filter (APF) is proposed for the linear degradation model. The proposed filter selects the image with the least deviation of noise component from among those minimizing the image component of the restored image in the averaged sense with respect to a set of original images. With the plain projection filter, the frequency of occurrence of images is ignored. In the averaged projection filter, the restoration quality of images occurring more frequently is improved at the expense of those occurring less frequently. A general form of the filter is obtained by using functional analysis. Some experimental results are illustrated which show the advantages of the proposed filter over the projection filter and the Wiener filter.

## Abstract We propose a method that uses multiple Wiener filters based on region decomposition to restore natural images degraded by Gaussian noise. Usually, a Wiener filter is designed to be optimal for the entire image. However, because natural images are highly nonstationary, an effective metho
A new iterative algorithm is presented for restoring noisy blurred images where the point spread function (PSF) is unknown. The method initially estimates the PSF and the original image using the Expectation Maximization (EM) method. The resulting image estimate is then refined by using the adaptive
