Classiication of Nonrigid Motion in 3d Images Using Physics-based Vibration Analysis

We present a method for comparison and classii-cation of nonrigid motion using a deformable model and the associated modal dynamics. Using the solid state physics formulation, we develop the equations of motion and the analytical expressions of vibration modes of a multidimensional elastically-deformable model that we use for tracking of nonrigid features in dynamic images. Thus, nonrigid motio...

Vibration Modes for Nonrigid Motion Analysis in 3D Images

We concentrate on nonrigid motion analysis in 3D images using modal dynamics. Borrowing the solid state physics formulation, we develop the equations of motion and the analytical expression of vibration modes of a multidimensional elastically-deformable model. Thus, nonrigid motion of a 3D deformable object can be recovered in closed-form in real time. The power of the approach is demonstrated ...

Active Animations of Reduced Deformable Models with Environment Interactions

We present an efficient spacetime optimization method to automatically generate animations for a general volumetric, elastically deformable body. Our approach can model the interactions between the body and the environment and automatically generate active animations. We model the frictional contact forces using contact invariant optimization and the fluid drag forces using a simplified model. ...

Global Motion Parameter Extraction and Deformable Block Motion Estimation

A global motion parameter estimation method is proposed. The method can be used to segment an image sequence into regions of different moving objects. For any two pixels belonging to the same moving object, their associated global motion components have a fixed relationship from the projection geometry of camera imaging. Therefore, by examining the measured motion vectors we are able to group p...
