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, ...
