1. A method of reducing noise associated with a series of images obtained from a moving target, comprising:

  • providing at least first and second frames of image data, each of said frames comprising a plurality of pixels;

    for said first frame, calculating the posterior probability that each of said plurality of pixels is a pixel of said target based at least in part on a prior probability;

    forming a posterior probability image based at least in part on said act of calculating;

    forming a reduced noise image by applying a filtering operation to said posterior probability image for use as a prior probability for at least said second frame; and

    providing said reduced noise image to a tracking system.
