FABRIK: A fast, iterative solver for the Inverse Kinematics problem
TLDR
A novel heuristic method, called Forward And Backward Reaching Inverse Kinematics (FABRIK), is described and compared with some of the most popular existing methods regarding reliability, computational cost and conversion criteria. Expand
New least squares solutions for estimating the average centre of rotation and the axis of rotation.
TLDR
A new method is proposed for estimating the parameters of ball joints, also known as spherical or revolute joints and hinge joints with a fixed axis of rotation, using the whole 3D motion data set and producing closed form solutions. Expand
Inverse Kinematics Techniques in Computer Graphics: A Survey
TLDR
This survey presents a comprehensive review of the IK problem and the solutions developed over the years from the computer graphics point of view, and suggests which IK family of solvers is best suited for particular problems. Expand
High angular resolution submillimeter observations of Sagittarius B2
Continuum observations of the Sgr B2 molecular cloud have been carried out. The data offer the first detailed description of the submillimeter radiation from this complex source. The emission isExpand
ChESS - Quick and robust detection of chess-board features
TLDR
Evidence is presented showing the ChESS feature detector, designed to exclusively respond to chess-board vertices, superior robustness, accuracy, and efficiency in comparison to other commonly used detectors, both under simulation and in experimental 3D reconstruction of flat plate and cylindrical objects. Expand
Inverse kinematics: a review of existing techniques and introduction of a new fast iterative solver
TLDR
This report reviews and compares the most popular IK methods regarding reliability, computational cost and conversion criteria, with a novel heuristic and iterative method, called Forward And Backward Reaching Inverse Kinematics (FABRIK). Expand
Section model tests on human – structure lock-in
In June/July 2000, shortly after the opening of the London Millennium Bridge, experiments were undertaken on a full-scale section model built to represent a footbridge swaying under pedestrianExpand
Motion capture with constrained inverse kinematics for real-time hand tracking
Articulated hand tracking systems have been commonly used in virtual reality applications, including systems with human-computer interaction or interaction with game consoles. However, building anExpand
A unified mathematical language for physics and engineering in the 21st century
TLDR
This paper will chart the resurgence of the algebras of Clifford and Grassmann in the form of a framework known as geometric algebra (GA), and discuss whether it is indeed the unifying language for the physics and mathematics of the 21st century. Expand
New Geometric Methods for Computer Vision: An Application to Structure and Motion Estimation
TLDR
A coordinate-free approach to the geometry of computer vision problems is discussed, believing the present formulation to be the only one in which least-squares estimates of the motion and structure are derived simultaneously using analytic derivatives. Expand
