Recent Submissions

Data-guided Model Predictive Control Based on Smoothed Contact Dynamics

Han, Daseong; Eom, Haegwang; Noh, Junyong; Shin, Joseph S. (formerly Sung Yong) (The Eurographics Association and John Wiley & Sons Ltd., 2016)

In this paper, we propose an efficient data-guided method based on Model Predictive Control (MPC) to synthesize a full-body motion. Guided by a reference motion, our method repeatedly plans the full-body motion to produce ...
Dexterous Manipulation of Cloth

Bai, Yunfei; Yu, Wenhao; Liu, C. Karen (The Eurographics Association and John Wiley & Sons Ltd., 2016)

This paper introduces a new technique to synthesize dexterous manipulation of cloth. Given a simple description of the desired cloth motion, our algorithm computes appropriate joint torques for physically simulated hands, ...
CAMA: Contact-Aware Matrix Assembly with Unified Collision Handling for GPU-based Cloth Simulation

Tang, Min; Wang, Huamin; Tang, Le; Tong, Ruofeng; Manocha, Dinesh (The Eurographics Association and John Wiley & Sons Ltd., 2016)

We present a novel GPU-based approach to robustly and efficiently simulate high-resolution and complexly layered cloth. The key component of our formulation is a parallelized matrix assembly algorithm that can quickly build ...
Single Image Weathering via Exemplar Propagation

Iizuka, Satoshi; Endo, Yuki; Kanamori, Yoshihiro; Mitani, Jun (The Eurographics Association and John Wiley & Sons Ltd., 2016)

This paper presents an efficient approach for generating weathering effects with detailed appearance variations in a single image. Previous approaches merely change chroma or reflectance of weathered objects, which is not ...
Interactive Videos: Plausible Video Editing using Sparse Structure Points

Chang, Chia-Sheng; Chu, Hung-Kuo; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Video remains the method of choice for capturing temporal events. However, without access to the underlying 3D scene models, it remains difficult to make object level edits in a single video or across multiple videos. While ...
Seamless Video Stitching from Hand-held Camera Inputs

Lin, Kaimo; Liu, Shuaicheng; Cheong, Loong-Fah; Zeng, Bing (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Images/videos captured by portable devices (e.g., cellphones, DV cameras) often have limited fields of view. Image stitching, also referred to as mosaics or panorama, can produce a wide angle image by compositing several ...
Multisampling Compressive Video Spectroscopy

Jeon, Daniel S.; Choi, Inchang; Kim, Min H. (The Eurographics Association and John Wiley & Sons Ltd., 2016)

The coded aperture snapshot spectral imaging (CASSI) architecture has been employed widely for capturing hyperspectral video. Despite allowing concurrent capture of hyperspectral video, spatial modulation in CASSI sacrifices ...
Inertial Steady 2D Vector Field Topology

Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Vector field topology is a powerful and matured tool for the study of the asymptotic behavior of tracer particles in steady flows. Yet, it does not capture the behavior of finite-sized particles, because they develop inertia ...
General Projective Maps for Multidimensional Data Projection

Lehmann, Dirk J.; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)

To project high-dimensional data to a 2D domain, there are two well-established classes of approaches: RadViz and Star Coordinates. Both are well-explored in terms of accuracy, completeness, distortions, and interaction ...
Anisotropic Diffusion Descriptors

Boscaini, Davide; Masci, Jonathan; Rodolà, Emanuele; Bronstein, Michael M.; Cremers, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Spectral methods have recently gained popularity in many domains of computer graphics and geometry processing, especially shape processing, computation of shape descriptors, distances, and correspondence. Spectral geometric ...
Space-Time Co-Segmentation of Articulated Point Cloud Sequences

Yuan, Qing; Li, Guiqing; Xu, Kai; Chen, Xudong; Huang, Hui (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Consistent segmentation is to the center of many applications based on dynamic geometric data. Directly segmenting a raw 3D point cloud sequence is a challenging task due to the low data quality and large inter-frame ...
Geometry and Attribute Compression for Voxel Scenes

Dado, Bas; Kol, Timothy R.; Bauszat, Pablo; Thiery, Jean-Marc; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Voxel-based approaches are today's standard to encode volume data. Recently, directed acyclic graphs (DAGs) were successfully used for compressing sparse voxel scenes as well, but they are restricted to a single bit of ...
VBTC: GPU-Friendly Variable Block Size Texture Encoding

Krajcevski, Pavel; Golas, Abhinav; Ramani, Karthik; Shebanow, Michael; Manocha, Dinesh (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Recent advances in computer graphics have relied on high-quality textures in order to generate photorealistic real-time images. Texture compression standards meet these growing demands for data, but current texture compression ...
Modeling and Estimation of Energy-Based Hyperelastic Objects

Miguel, Eder; Miraut, David; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2016)

In this paper, we present a method to model hyperelasticity that is well suited for representing the nonlinearity of real-world objects, as well as for estimating it from deformation examples. Previous approaches suffer ...
Effect of Low-level Visual Details in Perception of Deformation

Han, Donghui; Keyser, John (The Eurographics Association and John Wiley & Sons Ltd., 2016)

We quantitatively measure how different low-level visual details can influence people's perceived stiffness of a deformable sphere under physically based simulation. The result can be used to create a metric for artists ...
Learning 3D Deformation of Animals from 2D Images

Kanazawa, Angjoo; Kovalsky, Shahar; Basri, Ronen; Jacobs, David (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Understanding how an animal can deform and articulate is essential for a realistic modification of its 3D model. In this paper, we show that such information can be learned from user-clicked 2D images and a template 3D ...
Near-Instant Capture of High-Resolution Facial Geometry and Reflectance

BlendForces: A Dynamic Framework for Facial Animation

Barrielle, Vincent; Stoiber, Nicolas; Cagniart, Cédric (The Eurographics Association and John Wiley & Sons Ltd., 2016)

In this paper we present a new paradigm for the generation and retargeting of facial animation. Like a vast majority of the approaches that have adressed these topics, our formalism is built on blendshapes. However, where ...
Adapting Feature Curve Networks to a Prescribed Scale

Gehre, Anne; Lim, Isaak; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)

Feature curves on surface meshes are usually defined solely based on local shape properties such as dihedral angles and principal curvatures. From the application perspective, however, the meaningfulness of a network of ...
Compressed Multiresolution Hierarchies for High-Quality Precomputed Shadows

Scandolo, Leonardo; Bauszat, Pablo; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2016)

The quality of shadow mapping is traditionally limited by texture resolution. We present a novel lossless compression scheme for high-resolution shadow maps based on precomputed multiresolution hierarchies. Traditional ...
