A system, apparatus and methods are disclosed for the spatial and temporal processing of time dependant array data using analog signal processors. In one embodiment, a programmable array of switched capacitors is used to provide tunable parameters for controlling the desired processing of input data streams. The switched capacitor implementation of a spatial filter provides a massively parallel device that can be programmed to perform isotropic and spatially-oriented anisotropic filtering with low power demands. The system further includes the ability to combine differently filtered output streams with independent multiplicative weights. In another embodiment, the nonlinear spatio-temporal motion energy of a two-dimensional image stream data is computed. The spatial-temporal filter is able to combine multiple analog filters, both spatial and temporal, to perform complex spatial-temporal filtering operations implemented by Gaussian kernel filtering chips. It enables the use of analog spatial-temporal filtered data provided by the chip for computing scene motion energy.

Spatio-temporal filter and method

A smart array comprised an array of polymer grid triodes arrayed with a common polymer grid. In a preferred embodiment it is embodied as a conducting polymer device which provides local gain adjustment for video display such that the entire sensor dynamic range available, typically more than 16 bits in the infrared detector case, can be utilized locally to solve the intra-scene contrast problem. The array of polymer grid triodes with common grid can be utilized to process the image in analog form directly on the focal plane. Alternatively, the array of polymer grid triodes with common grid can be utilized to process the image after analog to digital conversion and integrated directly into the display.
