Intrinsic Local Symmetries: A Computational Framework
(The Eurographics Association, 2012)
We present a computational framework for finding metric-preserving tangent vector fields on surfaces, also known as Killing Vector Fields. Flows of such vector fields define self-isometries of the surface, or in other ...
Affine-Invariant Photometric Heat Kernel Signatures
(The Eurographics Association, 2012)
In this paper, we explore the use of the diffusion geometry framework for the fusion of geometric and photometric information in local shape descriptors. Our construction is based on the definition of a modified metric, ...
Articulated Motion Segmentation of Point Clouds by Group-Valued Regularization
(The Eurographics Association, 2012)
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 ...
