Affine-invariant diffusion geometry for the analysis of deformable 3D shapes
We introduce an (equi-)affine invariant diffusion geometry by which surfaces that go through squeeze and shear transformations can still be properly analyzed. The definition of an...

Alpha-shapes and flow shapes are homotopy equivalent
In this paper we establish a topological similarity between two apparently different shape constructors from a set of points. Shape constructors are geometric structures that tran...

Wideband Beamspace Processing Using Orthogonal Modal Beamformers
We introduce a novel beamspace processing structure that can be used for narrowband or wideband sources located either in nearfield or farfield of a sensor array. Main features o...
