Abstract

In conventional studies of facial caricature drawing, image processing of a face picture is performed, and feature points are extracted. A caricature is drawn based on these points. On the other hand, there have been few studies of facial caricature drawing based on impressions, which are subjective and dependent on the person who views the face. The purpose of this paper is to draw a facial caricature using linguistic expressions in order to reflect personal impressions of a face. Cheerfulness, gentleness, and so on are considered as impressions of a face. The drawn facial caricature can be modified by the use of linguistic terms. The concept of exaggeration, which is important for emphasis of personality in a caricature drawing, is also introduced by considering the line thickness and the exaggeration rate. Facial caricatures are evaluated by subjects who themselves draw them by the presented method, and also by other subjects, and the validity of the process is discussed.© 2001 Scripta Technica, Syst Comp Jpn, 32(10): 1–12, 2001
