Grouping corresponding parts in vision and audition using perceptual grouping among different sensations

In sensor fusion, output from various sensors is fused to obtain better information. In those systems, it is implicitly assumed that output from various sensors has originated from the same object. However, if sensors are mounted on a system without intension, the assumption is not feasible. In many sensor fusion systems, designers set up sensors to obtain output originated from the same object. In the present paper, in order to automatically find relationship among sensors, we propose laws for perceptual organization among different sensations referring to the laws for organization in one sensation in the Gestalt psychology. Then the foundation of the laws is examined in simple experiments. The experimental system consists of vision and audition. It extracts corresponding parts of the two sensation referring to changes of output from each sensation.
