A review of restoration experience from historical blackouts and a decision support framework for parallel restoration with a case study

Electric Power Systems Research
A power system restoration after a blackout is expected within 8-12 hours, but historical data suggest that it can take up to several days in some occasions.

Parallel iterative image restoration algorithms

Proceedings of the 32nd Midwest Symposium on Circuits and Systems, 2003
Three parallel iterative image restoration algorithms with and without preconditioning are proposed and analyzed. The first algorithm corresponds to a coarse-grained general-purpose multiprocessor computer, the second to a massively parallel computer with synchronization, and the third to a massively parallel computer without synchronization.

Parallel solution to the image restoration problem

17th Convention of Electrical and Electronics Engineers in Israel, 2002
This work shows that when a problem is defined using local characteristics, a parallel solution is easily attained. Image-processing is known to be a computation-intensive task, where processing time might be crucial. One such problem is the restoration of a deformed image.

A parallel algorithm for image information restoration

Proceedings Fourth International Conference/Exhibition on High Performance Computing in the Asia-Pacific Region, 2000
An image information restoration algorithm based on Long-Range correlation (LR-IIRA) can be efficiently applied in image interpretation, restoration, and error concealment. But this algorithm requires excessive computing time, which restricts its application on large-scale problems and real time problems.

Parallel Implementation of a 3D Nonlinear Restoration Algorithm

1998
Real imaging instruments introduce aberrations such as blurring and noise into observed images. Before any proper scientific interpretation and analysis can be carried out on such images, they must be processed further to remove the aberrations. This task is best performed by nonlinear, rather than linear, restoration incorporating a priori knowledge ...

A Distributed Strategy for Parallel Power System Restoration

2023 IEEE Belgrade PowerTech, 2023
This paper describes a novel distributed strategy for parallel power system restoration (PPSR). In particular, given an initial partition, as for instance the optimal partition in nominal (non-faulty) conditions, we propose a consensus-based strategy that allows nodes to migrate from one subsystem to another one, in order to minimize a cost function of

Image restoration using a parallel indentification and filtering procedure

ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In this paper a parallel identification scheme is presented to extend the fast parallel Kalman filter structure of [1] with an on-line identification procedure. It is shown that the identification problem can be specified as a parallel set of one-dimensional autoregressive moving average (ARMA) identification problems.

Sequential and parallel image restoration: neural network implementations

IEEE Transactions on Image Processing, 1994
Sequential and parallel image restoration algorithms and their implementations on neural networks are proposed. For images degraded by linear blur and contaminated by additive white Gaussian noise, maximum a posteriori (MAP) estimation and regularization theory lead to the same high dimension convex optimization problem.

P-LSR: A Parallel Algorithm for Line Scratch Restoration

Seventh International Workshop on Computer Architecture for Machine Perception (CAMP'05), 2006
Many algorithms have been proposed in literature for digital film restoration; unfortunately, none of them ensures a perfect restoration whichever is the image sequence to be restored. Here, we adopt an approach to digital scratch restoration based on the combination of relatively well settled distinct techniques.

Parallel Architectures For Iterative Image Restoration

1991
The recovery or restoration of an image that has been distorted is one of the most important problems in image processing applications. A number of algorithms or filters providing a solution to the image restoration problem, have appeared in the literature.
