Parallel Electric Field in Flux Restoration during Ultrafiltration

Separation Science and Technology, 1991
Ultrafiltration membrane permeability may be restored by applying an electric field parallel to the plane of the membrane in the feed compartment of ultrafiltration cells. Two different electrode arrangements are described. Under some conditions, flux restoration is complete.

Multiple Blur Images Restoration -- A Parallel Computing Approach

2012 Fourth International Conference on Computational Intelligence and Communication Networks, 2012
Image restoration is the process of recovering the original image from the degraded or noisy image. Blind Deconvolution Algorithm can be used where no information about PSF value, it restores image and PSF simultaneously. There are multiple noisy images for deblurring. The first task is original images are degraded by degradation model.

Parallelization of a Public Image Restoration Algorithm

2007
We 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.

Parallel deconvolution methods for three dimensional image restoration

SPIE Proceedings, 2003
Restoration by deconvolution of three-dimensional images that have been contaminated by noise and spatially invariant blur is computationally demanding. We describe efficient parallel implementations of iterative methods for image deconvolution on a distributed memory computing cluster.

Parallel image restoration with a two-dimensional likelihood-based algorithm

Applied Optics, 2002
We describe a pixelwise parallel algorithm for the restoration of images that have been corrupted by a low-pass optical channel and additive noise. This new algorithm is based on an iterative soft-decision method of error correction (i.e., turbo decoding) and offers performance on binary-valued imagery that is comparable to the Viterbi algorithm.

Parallel digital image restoration using adaptive VLSI neural chips

Proceedings., 1990 IEEE International Conference on Computer Design: VLSI in Computers and Processors, 2002
Real-time digital image restoration using massively parallel Hopfield neural chips is presented. An efficient mixed-signal VLSI design with analog circuitry to perform neural computation and digital circuitry to process multiple-bit pixel information greatly reduces the network size.

Regularized image restoration using sequential and parallel architectures

SPIE Proceedings, 1997
This paper presents discrete thresholded binary networks of the Hopfield-type as feasible configurations to perform image restoration with regularization. The typically large scale nature of image data processing is handled by partitioning these structures and adopting sequential or parallel update strategies on the partitions one at a time.

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.

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 ...
