3DMatch: Learning the Matching of Local 3D Geometry in Range Scans

Andy Zeng, Shuran Song, Matthias Nießner, Matthew Fisher, Jianxiong Xiao

arXiv 2016

In this paper, we introduce 3DMatch, a data-driven local feature learner that jointly learns a geometric feature representation and an associated metric function from a large collection of real-world scanning data.

Opt: A Domain Specific Language for Non-linear Least Squares Optimization in Graphics and Imaging

Zachery DeVito, Michael Mara, Michael Zollhoefer, Gilbert Bernstein, Jonathan Ragan-Kelley, Christian Theobalt, Pat Hanrahan, Matthew Fisher, Matthias Nießner

arXiv 2016

We propose a new language, Opt, in which a user simply writes energy functions over image- or graph-structured unknowns, and a compiler automatically generates state-of-the-art GPU optimization kernels.

PiGraphs: Learning Interaction Snapshots from Observations

Manolis Savva, Angel X. Chang, Pat Hanrahan, Matthew Fisher, Matthias Nießner

SIGGRAPH 2016

We learn a probabilistic model connecting human poses and arrangements of objects from observations of interactions collected with commodity RGB-D sensors. This model is encoded as a set of Prototypical Interaction Graphs (PiGraphs): a human-centric representation capturing physical contact and attention linkages between geometry and the human body.
