In this paper we propose a novel framework to unite a population to an optimal (unknown) pose through their mutual deformation. The registration criterion comprises three terms, the first imposes compactness on appearance of the registered population at the pixel level, the second tries to minimize the individual distances between all possible pairs of images, while the last is a regularization...

In this paper, a simplified, economical and highly accurate method for large deformation, post-buckling, analyses of frame-type structures is presented. Using the concepts of polar-decomposition of deformation, an explicit expression for the tangent stiffness matrix of a member/element of the frame, that accounts for the nonlinear bending-stretching coupling, is derived in closed form, at any p...

This paper presents a method for effectively modeling the outer surfaces of inlay/onlay prostheses restoring teeth that are partially destroyed. We exploit 3D mesh deformation techniques: direct manipulation free-form deformation (DMFFD) [9] and multiple wires deformation (MWD) [10] with three kinds of information: standard teeth models, scanned mesh data from the plaster cast of a patient's to...

Come with us to read a new book that is coming recently. Yeah, this is a new coming book that many people really want to read will you be one of them? Of course, you should be. It will not make you feel so hard to enjoy your life. Even some people think that reading is a hard to do, you must be sure that you can do it. Hard will be felt when you have no ideas about what kind of book to read. Or...

Fast and realistic soft-tissue deformation is an important feature for medical simulation environments. In this work we present a direct deformation approach for volumetric datasets which is completely performed on the GPU. It takes on the one hand advantage of a GPU's computing power; on the other hand deformation is easily combined with hardware-supported rendering. Our deformation technique ...

In this paper, we want to find a corner enhancement curve deformation approach. We consider General Geometric Heat Flow(GGHF) as a general deformation approach, and the evolution of curvature in the approach is derived. The criteria of curvature scale space are proposed and subjected to the GGHF. The conditions under which the corner can be enhanced are also studied. From all these constraints,...
