Abstract
This paper describes an experiment performed to clarify the meaning of psychological goodness of shapes, which is expected to be an useful tool in a heuristic method of computer vision. Factor analysis is carried out to find main factors representing geometrical features of random shapes used in our experiment. A psychological experiment is then performed to determine the order of goodness of these shapes. The result of this experiment is related to the geometrical factors drawn from the factor analysis. Finally, we obtain the factor ‘Simplicity’ representing goodness of shapes and four geometrical indices which are closely related to the factor.
