1. A computer implemented method comprising:

  • analyzing an image over a plurality of different scales, wherein analyzing includes;

    determining spectral characteristics of the image at each of the plurality of different scales;

    determining spatial characteristics of the image at each of the plurality of different scales;

    determining a segmentation pattern for the image at each of the plurality of different scales based on the spectral and spatial characteristics of that particular scale; and

    identifying objects in the image based on portions of the segmentation patterns that are scale-invariant over the plurality of different scales,wherein each of the segmentation patterns includes a plurality of segments, each segment having a boundary, and wherein identifying objects in the image further includes;

    super-positioning the segmentation patterns determined at each of the plurality of different scales; and

    determining which of the boundaries or portions thereof are overlapping over one or more of the super-positioned segmentation patterns, wherein the portions of the segmentation patterns that are scale-invariant correspond to the overlapping boundaries or portions thereof.
