Abstract: In this paper, first, the performance of the Wiener filter in the frequency domain for
image restoration is compared with that in the time domain for images degraded by white
noise. After finding that the Wiener filter in the frequency domain is better than that in the
Subspace Information Criterion for Image Restoration-Mean Squared Error Estimator for Linear Filters

ABSTRACT Most of the image restoration filters proposed so far include parameters that
control the restoration properties. For bringing out the optimal restoration performance, these
parameters should be determined so that a certain error measure such as the mean

ABSTRACT. We study a variable exponent model for image restoration in the case that the
exponent attains the critical value one. We prove existence and G-convergence. The results
answer an open question by Li, Li and Pi [Variable exponent functionals in image

Abstract—We present a general comparison of punctual kriging based image restoration for
different neighbourhood sizes. The formulation of the technique under consideration is
based on punctual kriging and fuzzy concepts for image restoration in spatial domain.

A Duijster, S De Backer Image Analysis and Recognition, 2007 ,Springer
In this paper, we study the problem of restoring multicomponent images. In particular, we
investigate the effects of accounting for the correlation between the image components on
the deconvolution and denoising steps. The proposed restoration is a 2-step procedure,

ABSTRACT We demonstrate the possibility of improving the standard Perona-Malik’s
anisotropic diffusion process for image restoration thanks to a constructive action of a
purposely injected noise. The effect is shown to be robustly preserved for various types of

ABSTRACT Considering the fact that the remote sensing image is mainly captured by a
linear CCD with the push-broom way which the image varies over time, the time-varying
wavelet packets for image restoration is proposed in the paper. On one hand, the result of

P Liu, Y Zhang ,Journal of Electronics (China), 2007 ,Springer
Abstract A GMM (Gaussian Mixture Model) based adaptive image restoration is proposed in
this paper. The feature vectors of pixels are selected and extracted. Pixels are clustered into
smooth, edge or detail texture region according to variance-sum criteria function of the

Abstract This paper shows how the performance of image processing algorithms can be
improved by reducing the noise influence on the restoration. A procedure, which we call
prefiltering, reduces this noisy sensitivity after the image has been acquired. It uses a local

Abstract Characteristical problem of multidimensional signal analysis and restoration is
processing of extremely big amounts of data as well as handling of data dependancies in
more than one direction. The problem of restoration can often be described as an ill-

Abstract. In this paper, we study an operator s which maps every n-by-n symmetric matrix An
to a matrix s (An) that minimizes Bn- An F over the set of all matrices Bn that can be
diagonalized by the sine transform. The matrix s (An), called the optimal sine transform

S Kim ,Computer Vision, Graphics and Image Processing, 2006 ,Springer
This article is concerned with new strategies with which explicit time-stepping procedures of
PDE-based restoration models converge with a similar efficiency to implicit algorithms.
Conventional explicit algorithms often require hundreds of iterations to converge. In order
