Abstract
A method and apparatus for an image processing system is provided. A first image and a second image in a sequence of images are registered to a reference image in the sequence of images to form a first registered image and a second registered image, respectively. A double differenced image is formed using the reference image, the first registered image, and the second registered image. A number of moving target signatures in the double differenced image is identified. A moving target signature in the number of moving target signatures comprises a spot of a first type and at least one spot of a second type adjacent to the spot of the first type.
