1. A method for automatically recognizing objects in digital image data, comprising:

  • detecting an object of interest in input digital image data;

    obtaining a normalized object of interest;

    assigning texton representations of the normalized object of interest to produce a first a texton array;

    determining a similarity between the texton representations and previously determined texton representations of at least one other object;

    detecting and normalizing a plurality of reference objects from a plurality of images;

    obtaining a first plurality of filter responses based upon pixels forming the plurality of normalized reference objects;

    forming a first plurality of vectors based upon the first plurality of filter responses; and

    clustering the first plurality of vectors into a plurality of groups, wherein each group is assigned a texton label.
