1. A method using an optical correlator, a preprocessor and a postprocessor for performing near real-time correlations between images of a sequence of images possibly containing an object of interest and electronically stored reference filters selected from a plurality of electronically stored reference filters each containing an optically modified reference view of an object of interest comprising:
A) storing said plurality of reference filters in a first electronic library,
B) electronically capturing an image of said sequence of images as an electronic representation,
C) selecting one or more of said reference filters likely to provide at least one correlation peak with said possible said object of interest in an electronically captured said image of said sequence of images,
D) using said optical correlator, rapidly comparing, in near real-time, each of said selected reference filters to said electronically captured image of said sequence of images,
E) using said post processor to identify those said selected reference filters having a highest correlation peak with said electronically captured image, and,
F) developing at least one feedback signal from step E) for predictably controlling and optimizing further selection of said reference filters and said preprocessor performing preconditioning of following electronically captured images of said sequence of images.
