Journal ArticleDOI
New least squares solutions for estimating the average centre of rotation and the axis of rotation.
TL;DR: 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.
Journal ArticleDOI
FABRIK: A fast, iterative solver for the Inverse Kinematics problem
Andreas Aristidou,Joan Lasenby +1 more
TL;DR: 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.
Journal ArticleDOI
Inverse Kinematics Techniques in Computer Graphics: A Survey
TL;DR: 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.
Journal ArticleDOI
New Geometric Methods for Computer Vision: An Application toStructure and Motion Estimation
TL;DR: 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.
Book
Applications of Geometric Algebra in Computer Science and Engineering
TL;DR: In this article, a generic framework for image geometry is presented, based on the Clifford Bracket Algebra, which can be used for image recognition in computer vision and robotics applications.
