## Abstract

In the computational theory of human vision, developed by D. Marr and his school zero-c.rossings detection is proposed as one of the fust stages of human visual information proc~ssing. The justification of this theory ~equues that the zero crossings are rich in Information about the original image. In a paper, T. Poggio, H.K. Nishihara and K.R.K . Nielsen stated that a successful extension of B. Logan's analysis to two-dimensional images represents one of the critical unsolved steps of this C<?mput!ltional ~heory. Moreover, such an extension IS crucial to the question of spatiotemporal interpolation in vision. In this paper, we shall provide a solution to this problem using a theory of spherical perspective and spherical harmonics.
