Connected Vibrations Method for Non-rigid Motion Tracking
نویسندگان
چکیده
This paper introduces a new algorithm for tracking nonrigid motion in image sequences. Non-rigid motions are modeled as the deformations of connected 2D membrane patches. Local smoothness constraints for each patch are the low-frequency vibration modes obtained from modal analysis. Hinges are imposed between patches to maintain the global topological structure. The resulted over-constrained linear system is solved e ciently using a least square estimator. Promising results on both natural and synthetic facial motion sequences are demonstrated in this paper.

Connected Vibrations: A Modal Analysis Approach for Non-Rigid Motion Tracking
A new framework is presented in this paper for tracking non-rigid motion in image sequences. This method models non-rigid motions as the deformations of connected 2D membrane patches. Local smoothness constraints for each patch are the low-frequency vibration modes obtained from modal analysis. These constraints are incorporated with the template matching algorithm into a local motion estimator...
متن کاملProbabilistic tracking and recognition of non-rigid human motion
Successful tracking of articulated hand motion is the first step in many computer vision applications such as gesture recognition. However the nonrigidity of the hand, complex background scenes, and occlusion make tracking a challenging task. We divide and conquer tracking by decomposing complex motion into non-rigid motion and rigid motion. A learning-based algorithm for analyzing non-rigid mo...

متن کاملJoint Bayes Filter: A Hybrid Tracker for Non-rigid Hand Motion Recognition
In sign-language or gesture recognition, articulated hand motion tracking is usually a prerequisite to behaviour understanding. However the difficulties such as non-rigidity of the hand, complex background scenes, and occlusion etc make tracking a challenging task. In this paper we present a hybrid HMM/Particle filter tracker for simultaneously tracking and recognition of non-rigid hand motion....
متن کاملQFT Control of a Two-Link Rigid-Flexible Manipulator
This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...
