Affine-invariant geodesic geometry of deformable 3D shapes
Dan Raviv, Alexander M. Bronstein, Michael M. Bronstein +2
Natural objects can be subject to various transformations yet still preserve properties that we refer to as invariants. Here, we use definitions of affine invariant arclength for s…
Affine-invariant diffusion geometry for the analysis of deformable 3D shapes
Dan Raviv, Alexander M. Bronstein, Michael M. Bronstein +2
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…
Diffusion-geometric maximally stable component detection in deformable shapes
Roee Litman, Alex M. Bronstein, Michael M. Bronstein
Maximally stable component detection is a very popular method for feature analysis in images, mainly due to its low computation cost and high repeatability. With the recent advance…
The Video Genome
Alexander M. Bronstein, Michael M. Bronstein, Ron Kimmel
Fast evolution of Internet technologies has led to an explosive growth of video data available in the public domain and created unprecedented challenges in the analysis, organizati…
