| Research Abstract |
This research project aimed to get some basic findings about the nature of human perception of three-dimensional structure resulted from two-dimensional motion information. For the purpose, at the beginning we reviewed past research results regarding perception of structure from motion, and carried out an experiment on perceptual interaction between boundary segmentation and surface interpolation processes appeared in structure-from-motion, which were summarized in two reports (in Japanese). Then we were concerned about speed perception of two-dimensional radial motion, and also about motion aftereffect induced by continuous viewing of two-dimensional expansion/contraction movement. Experimental results were summarized in another two reports (in Japanese) entitled "Speed perception of radial movement including spatial frequency gradients" and "Motion aftereffect for expansion and contraction movement including spatial frequency gradients." In addition, we tried a preliminary experiment on depth and motion perception by means of stereoscopic observation of successively displaced random-dot patterns.
