A statistical regularization framework for estimating normal displacements along contours with subpestricts the estimation to the only component that is locally reachable: the perpendicular-to-the-edge one. We model the moving edges as spatio-temporal surface patches in the image sequence space (.). A statistical regularization scheme based on Markov Random Fields allows us to get a homogeneous a

Computation of 3D-motion parameters using the log-polar transform,has been shown to be a variable resolution scheme that achieves a high compression of the non-foveal part of an image. Such space variant sensors must inevitably be active in order to utilize the high- and homogeneous resolution fovea. We study here the computation of the heading direction using a l

Generic 3-D shape model: Acquisitions and applications,al shapes in the training set are extracted automatically from the image sequences and represented by the control points of a B-spline surface. The generic model is derived by principal component analysis on the aligned training shapes. Using the acquired generic models, 3-D shape recovery, tracking

Guidelines for choosing optimal parameters of elasticity for snakes, A new two step procedure is defined based on upper and lower bounds on the parameters. Formulas, by which these bounds can be calculated for real images where parts of the contour may be missing, are presented. Experiments on segmentation of bone structures in X-ray images have verified the usefuln

Motion-based identification of deformable templates,ts environment can be represented by affine approximations. Based on hypotheses about these fields, an optimality principle is formulated to compute the shape of an object in terms of deformations of an arbitrary convex polygonal domain. As input data the algorithm merely requires first order deriva

Extending the Point Distribution Model using polar coordinates,tation lies in the fact that non-linear variation must be approximated by a combination of linear variations, resulting in a non-optimal model which can produce implausible object shapes. The Polynomial Regression PDM improves on the PDM by allowing polynomial deformation. However, computational com

Intermediate views for face recognition,ion of the face descriptors. Since the view based methods have been found to yield higher recognition rates, methods for generating synthetic intermediate views are necessary when a dense set of real views is not given. In many important applications only one or two real views are available. When tw

Rendering real-world objects without 3-D model, represent an object by a small set of corresponding 2-D views, and to construct any other view as a combination of these views. We show that this combination can be linear, assuming proximity of the views, and we suggest how the visibility of constructed points can be solved. Our approach entirely
