Convolutional neural networks have achieved extraordinary results in many computer vision and pattern recognition applications; however, their adoption in the computer graphics and geometry processing communities is limited due to the non-Euclidean structure of their data. In this paper, we propose Anisotropic Convolutional Neural Network (ACNN), a generalization of classical CNNs to non-Euclidean domains, where classical convolutions are replaced by projections over a set of oriented anisotropic diffusion kernels. We use ACNNs to effectively learn intrinsic dense correspondences between deformable shapes, a fundamental problem in geometry processing, arising in a wide variety of applications. We tested ACNNs performance in very challenging settings, achieving state-of-the-art results on some of the most difficult recent correspondence benchmarks.

Davide Boscaini (University of Lugano)

Davide Boscaini (MSc 2013, University of Verona, Italy) is a PhD candidate in the Institute of Computational Science, Faculty of Informatics at the University of Lugano (USI). His main research interests lie in the field of 3D shape analysis and synthesis, with a preference for approaches inspired by geometric intuitions. Recently, his research focussed on merging spectral approaches and machine learning techniques to develop novel algorithms for 3D shape analysis. A notable example includes the first intrinsic extension of the popular Convolutional Neural Networks paradigm to non-Euclidean domains.
