Abstract

This chapter presents an overview of the latest computerized artistic portrait rendering techniques. Artistic rendering of portraits can be viewed as an image generating process controlled by two factors. The first one is face fidelity, meaning a rendered portrait image should preserve a certain amount of the original face’s information. The second factor is the artistic style chosen to simulate different media such as sketch and painting. In the literature, portrait rendering algorithms either adopt different models and data structures to represent the facial information or use different graphical elements and compositional methods to simulate various media and styles. These two factors essentially reveal the two principles in portraiture, namely the pursuits of likeness and aesthetic.
