Abstract
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.
