Visual Analysis of Articulated Motion

by Philip A. Tresadern , 2006
"... The ability of machines to recognise and interpret human action and gesture from standard video footage has wide-ranging applications for control, analysis and security. However, in many scenarios the use of commercial motion capture systems is undesirable or infeasible (e.g. intelligent surveillanc ..."

From Motion (SFM), whereby point features on the surface of an articulated body impose constraints on the hidden joint locations, even for a single view. An alternative approach explores Machine Learning to employ context-specific

Articulated Motion Segmentation of Point Clouds by

by M. Spagnuolo, M. Bronstein, A. Bronstein, A. Ferreira (editors, Group-valued Regularization, G. Rosman, A. M. Bronstein, M. M. Bronstein, R. Kimmel
"... Motion segmentation for articulated objects is an important topic of research. Yet such a segmentation should be as free as possible from underlying assumptions so as to fit general scenes and objects. In this paper we demonstrate an algorithm for articulated motion segmentation of 3D point clouds, ..."

Articulated Motion Modeling for Activity Analysis

by Jiang Gao, Robert T. Collins, Alexander G. Hauptmann, Howard D. Wactlar - THIRD INTERNATIONAL CONFERENCE ON IMAGE AND VIDEO RETRIEVAL (CIVR'04), WORKSHOP ON ARTICULATED AND NONRIGID MOTION (ANM'04 , 2004
"... We propose an algorithm for articulated human motion segmentation that estimates parametric motions of body parts and segments images into moving regions accordingly. Our approach combines robust optical flow estimation, RANSAC, and region segmentation using color and Gaussian shape priors. This com ..."

Articulated Motion Segmentation Using RANSAC With Priors

by unknown authors
"... Articulated motions are partially dependent. Most of the existing segmentation methods, e.g. Costeira and Kanade[2], can not be applied to articulated motions. We propose a novel algorithm for articulated motion segmentation called RANSAC with priors. It does not require prior knowledge of the numbe ..."

Fast articulated motion tracking using . . .

by Carsten Stoll, Nils Hasler, Juergen Gall, Hans-peter Seidel, Christian Theobalt
"... We present an approach for modeling the human body by Sums of spatial Gaussians (SoG), allowing us to perform fast and high-quality markerless motion capture from multi-view video sequences. The SoG model is equipped with a color model to represent the shape and appearance of the human and can be re ..."

AN ARTICULATED MOTION AND VIBRATION ISOLATOR FOR SPACECRAFT

by Thomas W. Murphey, Matthew Botke, Ross M. Blankinship, Capt Nick, T. Hague
"... A novel concept is presented for motion and vibration isolation of a spacecraft from its subsystems. The isolator is an articulated chain of six rolamite joints arranged to give the spacecraft and subsystems full relative mobility (three translational and three rotational degrees of freedom). This m ..."

Rigid and Articulated Motion Seen with an Uncalibrated Stereo Rig

by Andreas Ruf, Radu Horaud - In IEEE Int. Conf. on Computer Vision , 1999
"... This paper establishes a link between uncalibrated stereo vision and the motion of rigid and articulated bodies. The variation in the projective reconstruction of a dynamic scene over time allows an uncalibrated stereo rig to be used as a faithful motion capturing device. We introduce an original th ..."

Tracking the Articulated Motion of Two Strongly Interacting Hands

by I. Oikonomidis, N. Kyriazis, A. A. Argyros
"... We propose a method that relies on markerless visual observations to track the full articulation of two hands that interact with each-other in a complex, unconstrained manner. We formulate this as an optimization problem whose 54dimensional parameter space represents all possible configurations of t ..."

by an RGB-D sensor. To the best of our knowledge, the proposed method is the first to attempt and achieve the articulated motion tracking of two strongly interacting hands. Extensive quantitative and qualitative experiments with simulated and real world image sequences demonstrate that an accurate
