Abstract : A method and system for classifying a raster scanned target image by collapsing the image into a vector corresponding to a horizontal line of the image, mathematically transforming this vector into a feature vector which corresponds to the power spectrum of the collapsed image, and comparing the feature vector with stored decision rules corresponding to classes of possible target objects to determine if the image represents an object in one of the classes.
