Measuring Visual Shape using Computer Graphics Psychophysics
This paper reviews recent psychophysical methods that have been developed for measuring the perceived shape of objects. We discuss two types of shape ambiguities that exist for many objects — a depth reversal ambiguity and an affine ambiguity. We show that people perceptually resolve these shape ambiguities by making strong prior assumptions the object.
