Abstract

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.
