WebAbstract. Vision is the process of inferring scene/world properties from images. Our specific concern is with image sequences and spatiotemporal variations in image intensity. It is therefore natural to begin with a discussion of image formation, the ways in which properties of the world are manifested in images as a function of time and space. WebImage formation involves the projection of points in (the world) to points in (the image plane).
