  • Electro-optical system for correlating and integrating image data from frame-to-frame
    Patent number: 4396903
    Abstract: An electro-optical system which integrates the image pattern information, extracted from a plurality of image frames and identified as belonging to a common candidate object, to form a composite image pattern of the candidate object which may be accurately classified with respect to a reference object image pattern is disclosed. More specifically, the formed composite image pattern of the candidate object is correlated with each image pattern of a set of reference object image patterns to generate a corresponding set of correlation values. Preferably, the largest of the correlation values is selected for a comparison with a threshold correlation value. In the event the generated correlation value exceeds the threshold correlation value, the candidate object represented by the composite image pattern is classified as the referenced object corresponding to the selected correlation value.
