Iterative color image restoration algorithms
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003Iterative techniques for restoring colour images are presented. These iterative algorithms have been developed for the restoration of monochromatic images. The colour images are modeled as three spatially related monochromatic images or channels. The interchannel correlation is incorporated into the iterative restoration algorithms in an indirect and ...

Constrained Iterative Restoration Algorithms
Proceedings of the IEEE, 1981This paper describes a rather broad class of iterative signal restoration techniques which can be applied to remove the effects of many different types of distortions. These techniques also allow for the incorporation of prior knowledge of the signal in terms of the specification of a constraint operator.

A parallel genetic algorithm for image restoration
Proceedings of 13th International Conference on Pattern Recognition, 1996A parallel genetic algorithm based on the island model for image restoration is presented. The algorithm divides a large population into smaller subpopulations and executes the main loop of the traditional genetic algorithm on each processor with its own subpopulation in parallel. Its performance is evaluated in a multi-workstation environment.

A new iterative algorithm for image restoration
Computer Vision, Graphics, and Image Processing, 1985Abstract A new technique for the restoration of linearly degraded images is presented. The method is applicable to both space variant and space invariant problems. It is an iterative procedure which is guaranteed to converge under very general conditions.

Restoration of Old Documents with Genetic Algorithms
2003Image recognition is a problem present in many real-world applications. In this paper we present an application of genetic algorithms (GAs) to solve one of those problems: the recovery of a deteriorated old document from the damages caused by centuries.

Fast algorithm for restoration of foggy images
2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013This paper describes a new fast method for foggy images restoration derived from the dark channel prior methodology. Based on a physical foggy image formation model, the parameters of the restoration algorithm are estimated from the saturation channel of a single colour image without any prior knowledge of the scene.

A POCS-Based Restoration Algorithm for Restoring Halftoned Color-Quantized Images
IEEE Transactions on Image Processing, 2006This paper studies the restoration of images which are color-quantized with error diffusion. Though there are many reported algorithms proposed for restoring noisy blurred color images and inverse halftoning, restoration of color-quantized images is rarely addressed in the literature especially when the images are color-quantized with halftoning ...

Adaptive algorithms that restore signal properties
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005This paper introduces the concept of designing adaptive filtering algorithms to exploit the presence of some invariant property possessed by a signal of interest. If this invariant property is disturbed by the interference or dispersion which degrades the signal's quality, and if the disturbance can be sensed, then it can be used to guide an adaptive ...

A spatiotemporal image sequence restoration algorithm
Proceedings. International Conference on Image Processing, 2003Temporal restoration of image sequences may fail because of erroneously estimated motion. Motion estimation failures may occur for several reasons -complicated motion, severe artefacts, or a combination of both. We present an algorithm that tries to overcome at least the problems related to severe artefacts.

Parallelization of a Public Image Restoration Algorithm
2007We present a deconvolution method intended for image restoration. Although the method is computationally heavy, it obtains a good restoration quality. We have successfully achieved the scientific aim of parallelizing the algorithm, obtaining acceptable scalability on shared and distributed memory machines.
