A Method of Non-Rigid Correspondence for AutomaticLandmark Identification
نویسندگان
چکیده
A method for corresponding the boundaries of two shapes is presented. The algorithm employs a sparse polygonal approximation of one of the boundaries, generated using a critical point detection algorithm. A matching sparse polygon is sought on the second of the two boundaries which is both similar in shape to and has a similar representation error to the rst. Optimisation of a cost function using a greedy algorithm locates the sparse polygon on the second boundary. Results are presented for three classes of shape which exhibit various types of non-rigid deformation. The algorithm is also applied to an automatic landmark identiication task.

On Two Methods for Computing the Non-Rigid Group of Molecules
In this paper, two methods are described, by means of which it is possible to calculate the non rigid group of molecules consisting of a number of XH3 groups attached to a rigid framework. The first method is a combination of the wreath product formalism of Balasubramanian and modern computer algebra and the second method is a computational approach by using group theory package GAP. We apply t...
متن کاملMass Properties Identification of a Rigid Body Using Modal Analysis
In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...
متن کاملNon-Rigid Spectral Correspondence of Triangle Meshes
We present an algorithm for finding a meaningful vertex-to-vertex correspondence between two triangle meshes, which is designed to handle general non-rigid transformations. Our algorithm operates on embeddings of the two shapes in the spectral domain so as to normalize them with respect to uniform scaling and rigid-body transformation. Invariance to shape bending is achieved by relying on appro...
متن کاملAn Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload
In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
متن کاملNonlinear inelastic dynamic analysis of space steel frames with semi-rigid connections in urban buildings
Applied studies addressing semi-rigid connections have been limited. Scant information exists in regulations except little brief information. Therefore, this research analyzes the behavior of three-dimensional steel frames and semi-rigid connections based on beam-column method and non-linear dynamic analysis. Stability functions and geometric stiffness matrix were used to study the non-linear g...
