Abstract

We present a novel method to model and estimate elastic geometric deformations of an observed object, whether they are caused by the object´s own dynamic behavior, or by the dynamic behavior of the imaging device, or both. A procedure for estimating the space of possible deformations the object may undergo based only on a set of observations is derived. This information is then employed to derive a linear estimator of the elastic deformation in any given observation. Application to change detection is presented.
