We present a new 1-D acoustooptic architecture to subtract two signals that are subpixel shifted. The architecture allows for optical interpolation and electrical control of the shift between frames. We demonstrate the use of 1-D projections of 2-D image frames to achieve subpixel shifts and interpolation between successive image frames for the purpose of detecting and tracking subpixel sized targets.
A Ho-Kashyap (H-K) associative processor (AP) is demonstrated to have a larger storage capacity than the pseudoinverse AP and to allow linearly dependent key vectors to be accurately stored. A new Robust H-K AP is sho...

Time sequential imagery is difficult to analyze, because of its high dimesionality. This paper advances a new algorithm that screens input data in an intelligent way, discards data with negligible information and uses...

We consider imaging spectrometer data as a large class problem (for which we offer a decision net solution involving a new hierachical classifier and set of multiple directed graphs) and as a mixture problem (for which a neural net solution is advanced).
We consider an analog (linear) heterodyned linear algebraic optical processor for adaptive phased array radar (APAR). Its use in solving the discrete steepest descent (DSD) algorithm is considered. New stability and p...
