We have developed a new optimization-based framework for computer vision that combines ideas from particle swarm optimization (PSO) and statistical pattern recognition to rapidly and accurately detect and classify objects in visual imagery. Swarm int

We compare neural network and genetic algorithm solutions of a resource allocation problem and discuss the relative asymptotic scaling of the two approaches in terms of time and space complexity. We show that for this problem neural networks and gene

Proceedings of the IEEE-SP International Symposium on Time-Frequency and Time-Scale Analysis (Cat. No.98TH8380).
Previously proposed methods for combining multiple spectrograms with different length analysis windows have been shown to result in improved time-frequency distributions (TFD) for certain classes of signals. Such TFDs are purely positive and have tim

We describe a laser diode-based optoelectronic implementation of artificial neural networks which utilizes real-time holography in photorefractive crystals. The use of a laser diode light source reduces the system size and power requirements. The hol

The STAP of radar signets involves solving a set of linear equations /spl Lambda/w=s. Here /spl Lambda/ is the correlation matrix of noise plus interference signals, w is the weight vector and s is the steering vector. The Weiner solution to estimate

We describe a Compensated Laser Ultrasonic Evaluation (CLUE™) system which combines a wavefront scrubbed laser receiver with a pulsed laser ultrasonic generator. The receiver uses nonlinear optics to compensate for the speckle produced by the surfa

The great success of conventional computers and procedural programming techniques in solving algorithmic problems in science and engineering contrasts with the far slower progress in solving the ill-defined problems at which humans and animals excel,

Photorefractive implementations of optical neural networks (ONN) can be divided into two architectures: stimulated and nonstimulated. In nonstimulated photorefractive ONN's, each connection weight is stored in the relatively well-defined grating that
