| Abstract(in English) | The purpose of this study is to investigate the human perception for the surface geometry of the face using shaded images based on three dimensional scanned face data. Subjects' task was to judge the local surface orientation observing five shaded images, 1)a normal face, 2)a reducing the number of data points of normal face(called pseudo face), 3)an upside-down normal face, 4)an upside-down pseudo face, 5)a Thatcher effect face. Subjects reported the local orientation at 227 point for each face stimuli. Results showed that reported surface orientation was rather stable for the normal face and human subjects could quantitaively judge the three dimensional surface geometry from shaded face images. |
