Reversible Jump Metropolis Light Transport Using Inverse Mappings
Benedikt Bitterli, Wenzel Jakob, Jan Novák, Wojciech Jarosz
Article No.: 1
DOI: 10.1145/3132704

We study Markov Chain Monte Carlo (MCMC) methods operating in primary sample space and their interactions with multiple sampling techniques. We observe that incorporating the sampling technique into the state of the Markov Chain, as done in...

Portrait Lighting Transfer Using a Mass Transport Approach
Zhixin Shu, Sunil Hadap, Eli Shechtman, Kalyan Sunkavalli, Sylvain Paris, Dimitris Samaras
Article No.: 2
DOI: 10.1145/3095816

Lighting is a critical element of portrait photography. However, good lighting design typically requires complex equipment and significant time and expertise. Our work simplifies this task using a relighting technique that transfers the desired...

Gigapixel Panorama Video Loops
Mingming He, Jing Liao, Pedro V. Sander, Hugues Hoppe
Article No.: 3
DOI: 10.1145/3144455

We present the first technique to create wide-angle, high-resolution looping panoramic videos. Starting with a 2D grid of registered videos acquired on a robotic mount, we formulate a combinatorial optimization to determine for each output pixel...

Learning Local Shape Descriptors from Part Correspondences with Multiview Convolutional Networks
Haibin Huang, Evangelos Kalogerakis, Siddhartha Chaudhuri, Duygu Ceylan, Vladimir G. Kim, Ersin Yumer
Article No.: 6
DOI: 10.1145/3137609

We present a new local descriptor for 3D shapes, directly applicable to a wide range of shape analysis problems such as point correspondences, semantic segmentation, affordance prediction, and shape-to-scan matching. The descriptor is produced by...
