A method for processing digital image representations representative of a subject head shape comprises: providing a database library of a first plurality of first digital image representations of subject head shapes captured directly from corresponding subjects, and a second plurality of second digital image representations of corresponding modified head shapes. The method includes proving a support vector machine and utilizing the database library plurality of said first and second digital image representation to train the support vector machine to operate on new digital image representations. The method further includes receiving a new digital image representation of a subject head shape captured directly from a new subject; and operating the support vector machine such that the support vector machine operates on the new first digital image representation to generate a corresponding new second digital image representation that replicates a corresponding modified head shape.
