Proc. SPIE, 1997 ,eecs.umich.edu
ABSTRACT We present a new class of algorithms for edge-preserving restoration of
piecewise-smooth images measured in non-Gaussian noise under shift-variant blur. The
algorithms are based on minimizing a regularized objective function, and are guaranteed

F Rooms, M Ronsse,    IEEE Signal Processing , 2002 ,filiprooms.be
ABSTRACT In this paper, a wavelet based method is proposed to estimate the blur in an
image using information contained in the image itself. We look at the sharpness of the
sharpest edges in the blurred image, which contain information about the blurring. 

On the choice of regularisation parameter in image restoration
J Kay ,Pattern Recognition, 1988 ,Springer
This paper considers the application of the method of regularisation within the context of the
restoration of degraded two-dimensional images. In particular, several recipes for choosing
an appropriate degree of regularisation are described and their performance compared

Abstract The design and analysis of an algorithm for the restoration of degraded images of
machine-printed characters is presented. The input is a set of degraded bilevel images of a
single unknown character; the output is an approximation to the character’s ideal artwork.

Computer Vision—ECCV’98, 1998 ,Springer
This article deals with the problem of restoring and segmenting noisy image sequences with
a static background. Usually, motion segmentation and image restoration are tackled
separately in image sequence restoration. Moreover, segmentation is often noise

MG Kang, AK Katsaggelos ,Optical Engineering- , 1994 ,ivpl.eecs.northwestern.edu
Abstract. An important consideration in regularized image restoration is the evaluation of the
regularization parameter. Various techniques exist in the literature for the evaluation of this
parameter, which depend on the assumed prior knowledge about the problem. These
