A sampling theoretical and experimental framework for the study of spatial vision is introduced. It is suggested that spatial Gestalt perception can be fruitfully analyzed by applying the concepts and methods of modern spatial filtering theory as they are known in the theory of image sampling and reconstruction. Demonstrations of the sampling processes in spatial vision are given and an experimental method for estimating the spatial reconstruction power of the human visual system is described. The experimental results presented suggest that high spatial frequency information has a special significance for human vision. Evidently, high frequency information is transmitted more easily through the visual system than has been generally assumed on the basis of contrast sensitivity studies.
