1. An automated method for decomposing a region in a radiographic image into subregions, comprising the steps of:

  • (a) smoothing the region at a plurality of scales to generate a plurality of smoothed regions;

    (b) computing, at each scale from each smoothed region, the number of connected components in each smoothed region;

    (c) determining the most stable range of scales and the most stable number of subregions contained within the range;

    (d) classifying each pixel based on the determined range of scales and the determined number of subregions; and

    (e) generating a decomposed map for further image processing.
