A caricature is defined as a humorous drawing of a human facial figure that makes
some of its distinct features appear exaggerated. It is easily observed that the
exaggerations made by different artists on facial components are often different and
are non-linear. This uniqueness of the exaggerations signifies the drawing style of an
artist, but has unfortunately been ignored in the design of existing computer based
automatic caricature generation systems. Nevertheless learning the unique drawing
style and modelling the non-linear exaggerations distinct to an artist provide the key
but a real challenge to the computer based automatic generation of professional
This Thesis proposes a face modelling framework that includes two novel face models,
which are capable of representing human faces in caricaturing applications. [Continues.]
