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.

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.

Identification and restoration using parallel Kalman filters

26th IEEE Conference on Decision and Control, 1987
In this paper a parallel identification and restoration procedure is described for images with symmetric, noncausal blurs. It is shown that the identification problem can be specified as a parallel set of one-dimensional complex autoregressive moving-average (ARMA) identification problems.

Parallel architectures for an iterative image restoration algorithm

IEEE International Symposium on Circuits and Systems, 2002
Mesh of pyramids and pyramid of meshes implementations of an iterative image-restoration algorithm are proposed. These implementations are based on a single-step regularized iterative restoration algorithm. Both architectures are described as a composition of a mesh and a pyramid.

Miniature parallel pins for retention of cast restorations

The Journal of Prosthetic Dentistry, 1961
Abstract The use of miniature parallel pinholes in cavity preparations for cast gold restorations permits the dentist to use a less stereotyped cavity design. A method of achieving parallelism in alignment of pinholes with subsequent alteration in cavity design has been described.

Parallel supramammillary-hippocampal routes: Organization, dysregulation, and restoration

Neuron
In this issue of Neuron, Luo et al.1 report two supramammillary neuronal populations with segregated projections to the dorsal and ventral dentate gyrus that selectively modulate cognitive and emotional processes, respectively. Targeted activation of each pathway alleviates domain-specific behavioral deficits in an Alzheimer's disease mouse model.
