A method for 3D face modeling and caricatured figure generation

This paper proposes a method for modeling a subject with a 3D face from 2D facial images captured from surrounding 2D cameras which synchronously measure the color, texture and surface shape information of the face. The 3D facial caricaturing method uses a 3D (polygon data) face model. An automatic method for extracting regions of the facial parts is technically proposed, and the feature points are extracted from those regions. We propose a wire frame model composed of 44 feature points and 82 polygons to cover a head. To generate a caricature from the polygon data, the individuality feature is defined by the difference of the feature points between the input face and the mean face, which was defined from the average of many input faces. We also propose a method for producing the 3D figure of a human facial caricature.
