1. A method of analyzing a matrix of pixel values representing an Analysis Image that is a function of pixel values representing an Original Image derived from an image source wherein the matrices representing the Analysis Image and the Original Image are either the same or different, comprising:

  • (1) selecting (a) a process applicable to a class of images of which the Original Image is member, and (b) specification information for the class of images of which the Original image is a member;

    (2) deriving information from the pixel values of the Original Image, and generating a matrix of pixel values for a corresponding Analysis Image as indicated by the specification information selected in step (1);

    (3) generating a set of binary images from data representing the Analysis Image data as indicated by the specification information selected in step (1);

    (4) modeling the binary images of the set by using fractal geometry using specification information selected in step (1), each binary model being uniquely specified by (a) a set of independent affine transformation parameters, (b) relationships whereby the remaining parameters necessary to uniquely specify affine transformations are derived from the parameters specified in (a), (c) specifications obtained in step (1) and (d) other data derived from the pixel values of the Analysis Image; and

    (5) generating a signal containing information about the image source in response to the affine transformation parameters, specifications, and derived data obtained in step (4).
