Non-rigid Transformations for Musculoskeletal Model
نویسنده
چکیده
This paper provides describes solution for the fully automatic registration and multi-morphing of surface triangular meshes. It solves the instability problem experienced with non-manifold mesh transformations. A refinement and interpolation of multiple such meshes representing the same object are used to obtain one manifold mesh for later processing. Details can be found in [2].

Compensation of brain shift during surgery using non-rigid registration of MR and ultrasound images
Background: Surgery and accurate removal of the brain tumor in the operating room and after opening the scalp is one of the major challenges for neurosurgeons due to the removal of skull pressure and displacement and deformation of the brain tissue. This displacement of the brain changes the location of the tumor relative to the MR image taken preoperatively. Methods: This study, which is done...
متن کاملPolyrigid and polyaffine transformations: A novel geometrical tool to deal with non-rigid deformations - Application to the registration of histological slices
We describe in this paper a novel kind of geometrical transformations, named polyrigid and polyaffine. These transformations efficiently code for locally rigid or affine deformations with a small number of intuitive parameters. They can describe compactly large rigid or affine movements, unlike most free-form deformation classes. Very flexible, this tool can be readily adapted to a large variet...
متن کاملDiffeomorphic Registration Using B-Splines
In this paper we propose a diffeomorphic non-rigid registration algorithm based on free-form deformations (FFDs) which are modelled by B-splines. In contrast to existing non-rigid registration methods based on FFDs the proposed diffeomorphic non-rigid registration algorithm based on free-form deformations (FFDs) which are modelled by B-splines. To construct a diffeomorphic transformation we com...
متن کاملVessel to Image Registration using Rigid and Elastic Transformations
Several recent studies demonstrate a real potential in taking tubular structures as a base for image registration. In this paper, we present a novel technique to conduct deformations on tubular structures. Our approach aligns a pre-extracted tubular model, e.g. vessels inside an organ or a set of bones, with an image by combining both rigid and elastic transformations. The physical structure an...
متن کاملOptimizing the actuation of musculoskeletal model by genetic algorithm to simulate the vertical jump
In human body movement simulation such as vertical jump by a forward dynamic model, optimal control theories must be used. In the recent years, new methods were created for solving optimization problems which they were adopted from animal behaviors and environment events such as Genetic algorithm, Particle swarm and Imperialism competitive. In this work, the skeletal model was constructed by Ne...
