  • Method and System for Determining Compactness of an Object
    Publication number: 20070206864
    Abstract: Disclosed is a method and apparatus for determining the compactness of a digital representation of an object. A kernel (which is smaller than the object itself) is positioned at the geographic center of the object. The kernel's dimensions are then uniformly expanded. A first radius of the kernel is determined when a portion of the kernel is first located outside of the object, A second radius of the kernel is determined when the kernel first overlaps the object. The compactness of the object is then determined using the first radius and the second radius.

  • System and method for characterizing 2-dimensional shapes by compactness measurements
    Publication number: 20060110048
    Abstract: A method of classifying a shape in a digitized image includes determining a normalized compactness CDN for an object in said image from the formula C DN = Tn - P Tn - 4 ? n , wherein T is the connectivity of the object, n is the number of pixels in the object, and P is the length of the perimeter of the object, and classifying said object based on its normalized compactness value.
