EyeOpener: Editing Eyes in the Wild
Zhixin Shu, Eli Shechtman, Dimitris Samaras, Sunil Hadap
Article No.: 1
DOI: 10.1145/2926713

Closed eyes and look-aways can ruin precious moments captured in photographs. In this article, we present a new framework for automatically editing eyes in photographs. We leverage a user’s personal photo collection to find a...

Interactive Sound Propagation and Rendering for Large Multi-Source Scenes
Carl Schissler, Dinesh Manocha
Article No.: 2
DOI: 10.1145/2943779

We present an approach to generate plausible acoustic effects at interactive rates in large dynamic environments containing many sound sources. Our formulation combines listener-based backward ray tracing with sound source clustering and hybrid...

Interpolations of Smoke and Liquid Simulations
Nils Thuerey
Article No.: 3
DOI: 10.1145/2956233

We present a novel method to interpolate smoke and liquid simulations in order to perform data-driven fluid simulations. Our approach calculates a dense space-time deformation using grid-based signed-distance functions of the inputs.

A key...

A Spatial Target Function for Metropolis Photon Tracing
Adrien Gruson, Mickaël Ribardière, Martin Šik, Jiří Vorba, Rémi Cozot, Kadi Bouatouch, Jaroslav Křivánek
Article No.: 4
DOI: 10.1145/2963097

The human visual system is sensitive to relative differences in luminance, but light transport simulation algorithms based on Metropolis sampling often result in a highly nonuniform relative error distribution over the rendered image. Although...

A Compressed Representation for Ray Tracing Parametric Surfaces
Kai Selgrad, Alexander Lier, Magdalena Martinek, Christoph Buchenau, Michael Guthe, Franziska Kranz, Henry Schäfer, Marc Stamminger
Article No.: 5
DOI: 10.1145/2953877

Parametric surfaces are an essential modeling tool in computer aided design and movie production. Even though their use is well established in industry, generating ray-traced images adds significant cost in time and memory consumption. Ray tracing...

PERFORM: Perceptual Approach for Adding OCEAN Personality to Human Motion Using Laban Movement Analysis
Funda Durupinar, Mubbasir Kapadia, Susan Deutsch, Michael Neff, Norman I. Badler
Article No.: 6
DOI: 10.1145/2983620

A major goal of research on virtual humans is the animation of expressive characters that display distinct psychological attributes. Body motion is an effective way of portraying different personalities and differentiating characters. The purpose...

Decomposing Images into Layers via RGB-Space Geometry
Jianchao Tan, Jyh-Ming Lien, Yotam Gingold
Article No.: 7
DOI: 10.1145/2988229

In digital image editing software, layers organize images. However, layers are often not explicitly represented in the final image, and may never have existed for a scanned physical painting or a photograph. We propose a technique to decompose an...

Virtual Rephotography: Novel View Prediction Error for 3D Reconstruction
Michael Waechter, Mate Beljan, Simon Fuhrmann, Nils Moehrle, Johannes Kopf, Michael Goesele
Article No.: 8
DOI: 10.1145/2999533

The ultimate goal of many image-based modeling systems is to render photo-realistic novel views of a scene without visible artifacts. Existing evaluation metrics and benchmarks focus mainly on the geometric accuracy of the reconstructed model,...

Antialiasing Complex Global Illumination Effects in Path-Space
Laurent Belcour, Ling-Qi Yan, Ravi Ramamoorthi, Derek Nowrouzezahrai
Article No.: 9
DOI: 10.1145/2990495

We present the first method to efficiently predict antialiasing footprints to pre-filter color-, normal-, and displacement-mapped appearance in the context of multi-bounce global illumination. We derive Fourier spectra for radiance and importance...

Momentum-Mapped Inverted Pendulum Models for Controlling Dynamic Human Motions
Taesoo Kwon, Jessica K. Hodgins
Article No.: 10
DOI: 10.1145/2983616

Designing a unified framework for simulating a broad variety of human behaviors has proven to be challenging. In this article, we present an approach for control system design that can generate animations of a diverse set of behaviors including...

Retrieval on Parametric Shape Collections
Adriana Schulz, Ariel Shamir, Ilya Baran, David I. W. Levin, Pitchaya Sitthi-Amorn, Wojciech Matusik
Article No.: 11
DOI: 10.1145/2983618

While collections of parametric shapes are growing in size and use, little progress has been made on the fundamental problem of shape-based matching and retrieval for parametric shapes in a collection. The search space for such collections is both...

Optimal Discrete Slicing
Marc Alexa, Kristian Hildebrand, Sylvain Lefebvre
Article No.: 12
DOI: 10.1145/2999536

Slicing is the procedure necessary to prepare a shape for layered manufacturing. There are degrees of freedom in this process, such as the starting point of the slicing sequence and the thickness of each slice. The choice of these parameters...
