  Synthesizing 3D faces that give certain personality impressions is commonly
needed in computer games, animations, and virtual world applications for
producing realistic virtual characters. In this paper, we propose a novel
approach to synthesize 3D faces based on personality impression for creating
virtual characters. Our approach consists of two major steps. In the first
step, we train classifiers using deep convolutional neural networks on a
dataset of images with personality impression annotations, which are capable of
predicting the personality impression of a face. In the second step, given a 3D
face and a desired personality impression type as user inputs, our approach
optimizes the facial details against the trained classifiers, so as to
synthesize a face which gives the desired personality impression. We
demonstrate our approach for synthesizing 3D faces giving desired personality
impressions on a variety of 3D face models. Perceptual studies show that the
perceived personality impressions of the synthesized faces agree with the
target personality impressions specified for synthesizing the faces. Please
