Automatic Caricature Generation by Analyzing Facial Features

Abstract

We developed a system for automatic generation of caricatures by analyzing unique facial features of the subject. The proposed face model contains 119 parameters derived from the MPEG-4 standard. These nodes are categorized into 8 groups with a pre-defined hierarchy to guide the placement of face components after shape exaggeration. Given an input image, the system determines which and how the face component should be altered. Using an artist’s finished work as the source image, the system is capable of producing caricatures of a similar style effectively and efficiently.
