摘要：

In computer vision and image understanding research, rigidity of bodies and their motions has long been a key assumption in obtaining 3-dimensional shape and motion information from 2-dimensional images. In this paper, the rigidity assumption is relaxed in several fundamental problems. Nonrigid, elastic bodies under perspective projection are considered. Deformations of such bodies are diffeomorphisms of R**3 in the case of static elasticity. For dynamic elasticity, generalized motions (including deformations) are represented by 1-parameter families of diffeomorphisms of R**3. The primary goal is to determine a generalized motion of a known nonrigid, elastic body given images of the body before and after the generalized motion.
