Direct finite element solution on an optical laboratory matrix-vector processor

TL;DR: The first optical laboratory system results employing a direct LU decomposition solution of a system of linear algebraic equations are presented for a finite element problem solution and the first laboratory demonstration of the use of sign-magnitude negative number representation.
Proceedings ArticleDOI

Pose-invariant recognition of faces at unknown aspect views

TL;DR: A new technique is discussed to recognize human faces under varying aspect views (pose) using a feature extraction procedure that inherently removes distortions due to pose variations, and therefore requires only single training and/or test face images, which could be at different aspect views.
Proceedings ArticleDOI

Optimality Considerations In Modified Matched Spatial Filters

TL;DR: In this article, general expressions for the degradation in signal to noise ratio (SNR) as a function of rotation and scale distortions for modified matched spatial filters (MSFs) were derived.
Journal ArticleDOI

Accuracy and space bandwidth in space variant optical correlators

TL;DR: In this article, the required space bandwidth of these optical pattern recognition systems and the resultant accuracy of these novel deformation invariant correlators were considered. But the accuracy of the correlators was not evaluated.
