Metric-aware processing of spherical imagery
Found in: ACM Transactions on Graphics (TOG)
By Hugues Hoppe, Michael Kazhdan, Hugues Hoppe, Michael Kazhdan
Issue Date:December 2010
pp. 1-12
Processing spherical images is challenging. Because no spherical parameterization is globally uniform, an accurate solver must account for the spatially varying metric. We present the first efficient metric-aware solver for Laplacian processing of spherica...

We describe a scalable database cluster for the spatial analysis and annotation of high-throughput brain imaging data, initially for 3-d electron microscopy image stacks, but for time-series and multi-channel data as well. The system was designed primarily...
     
Screened poisson surface reconstruction
Found in: ACM Transactions on Graphics (TOG)
By Hugues Hoppe, Michael Kazhdan
Issue Date:June 2013
pp. 1-13
Poisson surface reconstruction creates watertight surfaces from oriented point sets. In this work we extend the technique to explicitly incorporate the points as interpolation constraints. The extension can be interpreted as a generalization of the underly...

A real-time screened-Poisson solver for interactive surface editing
Found in: Proceedings of the 2010 ACM SIGGRAPH symposium on Interactive 3D Graphics and Games (I3D '10)
By Michael Kazhdan, Ming Chuang
Issue Date:February 2010
pp. 1-1
We describe a real-time system for editing large 3D meshes. The system supports both global and local modulation of surface detail, expressing the position of vertices on the edited geometry as the solution to a linear system of equations defined over the ...
     
Streaming multigrid for gradient-domain operations on large images
Found in: ACM Transactions on Graphics (TOG)
By Hugues Hoppe, Michael Kazhdan
Issue Date:August 2008
pp. 1-49
We introduce a new tool to solve the large linear systems arising from gradient-domain image processing. Specifically, we develop a streaming multigrid solver, which needs just two sequential passes over out-of-core data. This fast solution is enabled by a...
