Abstract:
1. A target identification system for identifying targets in an input image, said system comprising: a plurality of feature extractors, each for extracting a particular feature from an image and producing a resulting modified image; a plurality of normalizers, each coupled to a corresponding one of the plurality of feature extractors, for normalizing the corresponding modified image across the image, such that the feature value at each pixel of the modified image represents the number of standard deviations that the pixel stands apart from values for the same feature across the image, each of said plurality of normalizers outputting a corresponding normalized modified image; means for combining the plurality of normalized modified images to produce a combined image having a plurality of confidence values for a plurality of pixels within the image; and means for extracting a list of potential targets from the combined image, each of the list of potential targets having an associated confidence value.
