Change of constraints in rope articulated structures

Linear recovery of articulated pose change : comparing pre - and post - imposed constraints

This paper contrasts two methods of imposing constraints during the tracking of articulated objects. The first method develops constraints using a conventional kinematical approach, but in a novel extension of Harris' RAPiD rigid body tracker. This generates a linear system for pose update in terms of the minimal set of variables describing the six degrees of freedom of a base subpart and the j...

Tracking Articulated Structures in Stereo Image Sequences

| In this paper, we present an algorithm for real time 3-D tracking of articulated structures in stereo image sequences. These sequences can be captured by an inexpensive commercially available system that also computes the dense disparity map in real time. In our algorithm, the tracked object is modeled as a set of articulated 3D blobs, each adhering to a Gaussian distribution. Classi cation o...

Appearance-Based Tracking of 3D Articulated Structures

This article describes a method to track 3D articulated structures from a monocular perspective image sequence using a particle filter. This structure is composed of a set of linked degenerated quadrics (cones), which are truncated, by pairs of planes also modelled as degenerated quadrics. Joints containing one or more degrees of freedom connect this set of truncated cones. The method is based ...

non-linear study of various slit shear walls in steel structures

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
