| Abstract(in English) | Asakura and Ohmi (2004) have proposed a theoretical framework for the perception of 3-D structure from motion that builds on the concepts of a generative model and model selection. The framework assumes that by making use of generative models of moving images due to rigid and nonrigid motion, the human visual system generates predictions of an incoming moving image, and selects an appropriate model for the recovery of 3-D structure from a given moving image, on the basis of the compatibility between the given image data and its predictions. In this study, we extend the framework to incorporate a strong interaction between motion and contrast cues into the generative models for rigid and nonrigid motion. This new framework leads to an empirically testable prediction: rigid motion displays tend to be perceived as nonrigid when motion and contrast cues are temporally incosistent. We present its supporting psychophysical evidence and discuss the process of integrating motion and contrast information. |
