Abstract
Optic flow has shown to be a rich source of 3-dimensional scene structure. In this work we report on an approach that induces optic flow without camera motion. This approach has been suggested before but the core issue, shape matching across focal lengths was not addressed. We propose a model-based matching technique based on the physics of optical zooming
