Abstract: A method and apparatus for processing imagery using images acquired via any known Electro-Optical (EO) system. In accordance with exemplary embodiments of the present invention, a first frame of data is selected as a template frame (e.g., a given frame). A second frame of data can be captured using the EO system. At least a portion of the second frame can be correlated with the template frame to generate a shift vector. The second frame can then be registered with the template frame by interpolating the second frame using the shift vector and re-sampling at least a portion of the second frame to produce a registered frame. The template frame can also be re-sampled. The registered frame and the re-sampled template frame can then be combined to generate an averaged frame. The averaged frame can be spatially filtered to enhance edges within the averaged frame.

Abstract: A digital signal processing system which uses an input image including a plurality of pixels to establish boundaries of objects in the input image. Each of the pixels has a gradient value and the object includes a centroid. Using a segmentation process, the digital signal processing system decides on a perimeter surrounding the object in the input image and then repeatedly searches for a pixel having the highest gradient value and marks that pixel having the highest gradient value as an edge pixel of the object.

Abstract: A memory controller includes an input data path and an output data path. First circuitry generates signals to put the input data into at least one variably-dimensioned logical array of memory cells of a memory. Second circuitry generates signals to extract from the memory the contents of at least one variably-dimensioned logical array of memory cells. The memory may be double buffered such that data input to one of the portions may take place simultaneously as data output from the other of the portions. In a preferred embodiment, any combination of up to 254 total variable-dimensioned logical arrays of memory cells may be defined for input to and output from the memory. The memory controller may be viewed as supporting two simultaneous processes, an input "windowing" process for receiving windows of data and an output "windowing" process for simultaneously passing out windows of data.

Abstract: A targeting system which receives input data from two sources having different video characteristics. The apparatus includes a multiple-pass centroid eroder, which operates at a multiple of the video input rate. The apparatus identifies "hot spots," i.e., potential targets, and uses the identified potential targets from the two video sources to correlate targeting of submodules producing the two video signals.

Abstract: A parallel data processor comprised of an array of identical cells concurrently performing identical operations under the direction of a central controller, and incorporating one or more of a special cell architecture including a segmented memory, conditional logic for preliminary processing, and circuitry for indicating when the cell is active, and programmable cell interconnection including cell bypass and alternate connection of edge cells.
