Smoothed Local Histogram Filters Michael Kass, Justin Solomon May 2010 Local image histograms contain a great deal of information useful for applications in computer graphics, computer vision and computational photography. Making use of that information has been challenging because of the expense of computing histogram properties over large neighborhoods. Efficient algorithms exist for some specific computations like the bilateral filter, but not others. ... more Paper (PDF) To appear in the Proceedings of SIGGRAPH 2010 Available as Pixar Technical Memo #10-02 |

Convolutional Wasserstein Distances: Efficient Optimal Transportation on Geometric Domains Justin Solomon, Fernando de Goes, Gabriel Peyre, Marco Cuturi, Adrian Butscher, Andy Nguyen, Tao Du, Leonidas Guibas August 2015 This paper introduces a new class of algorithms for optimization problems involving optimal transportation over geometric domains. Our main contribution is to show that optimal transportation can be made tractable over large domains used in graphics, such as images and triangle meshes, improving performance by orders of magnitude compared to ... more Paper (PDF) SIGGRAPH 2015 |
