Constructing geometric object models from images

This paper addresses the problem of constructing object models from various types of images. After a brief discussion of current approaches to this problem, we focus on two of its instances: the construction of three-dimensional surface models from object outlines found in a small set of registered photographs; and the synthesis of new images of a scene without any explicit three-dimensional reconstruction (image-based rendering). In both cases, we discuss the state of the art and present some of our recent work as an illustration of what can be achieved today.
