Approximate Program Smoothing Using Mean-Variance Statistics, with Application to Procedural Shader Bandlimiting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We introduce a general method to approximate the convolution of a program with a Gaussian kernel. This results in the program being smoothed. Our compiler framework models intermediate values in the program as random ... -
Procedural Cloudscapes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a phenomenological approach for modeling and animating cloudscapes. We propose a compact procedural model for representing the different types of cloud over a range of altitudes. We define primitive-based field ... -
Procedural Modeling of a Building from a Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Creating a virtual city is demanded for computer games, movies, and urban planning, but it takes a lot of time to create numerous 3D building models. Procedural modeling has become popular in recent years to overcome this ... -
Example-based Authoring of Procedural Modeling Programs with Structural and Continuous Variability
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Procedural models are a powerful tool for quickly creating a variety of computer graphics content. However, authoring them is challenging, requiring both programming and artistic expertise. In this paper, we present a ... -
Deep Joint Design of Color Filter Arrays and Demosaicing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a convolutional neural network architecture for performing joint design of color filter array (CFA) patterns and demosaicing. Our generic model allows the training of CFAs of arbitrary sizes, optimizing each ... -
Single-image Tomography: 3D Volumes from 2D Cranial X-Rays
(The Eurographics Association and John Wiley & Sons Ltd., 2018)As many different 3D volumes could produce the same 2D x-ray image, inverting this process is challenging. We show that recent deep learning-based convolutional neural networks can solve this task. As the main challenge ... -
Practical Radiometric Compensation for Projection Display on Textured Surfaces using a Multidimensional Model
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Radiometric compensation methods remove the effect of the underlying spatially varying surface reflectance of the texture when projecting on textured surfaces. All prior work sample the surface reflectance dependent ... -
Hair Modeling and Simulation by Style
(The Eurographics Association and John Wiley & Sons Ltd., 2018)As the deformation behaviors of hair strands vary greatly depending on the hairstyle, the computational cost and accuracy of hair movement simulations can be significantly improved by applying simulation methods specific ... -
Sequences with Low-Discrepancy Blue-Noise 2-D Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Distributions of samples play a very important role in rendering, affecting variance, bias and aliasing in Monte-Carlo and Quasi-Monte Carlo evaluation of the rendering equation. In this paper, we propose an original sampler ... -
Semantic Segmentation for Line Drawing Vectorization Using Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this work, we present a method to vectorize raster images of line art. Inverting the rasterization procedure is inherently ill-conditioned, as there exist many possible vector images that could yield the same raster ... -
Flexible Live-Wire: Image Segmentation with Floating Anchors
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We introduce Flexible Live-Wire, a generalization of the Live-Wire interactive segmentation technique with floating anchors. In our approach, the user input for Live-Wire is no longer limited to the setting of pixel-level ... -
Aura Mesh: Motion Retargeting to Preserve the Spatial Relationships between Skinned Characters
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Applying motion-capture data to multi-person interaction between virtual characters is challenging because one needs to preserve the interaction semantics while also satisfying the general requirements of motion retargeting, ... -
Self-similarity Analysis for Motion Capture Cleaning
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Motion capture sequences may contain erroneous data, especially when the motion is complex or performers are interacting closely and occlusions are frequent. Common practice is to have specialists visually detect the ... -
Real-time Locomotion Controller using an Inverted-Pendulum-based Abstract Model
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we propose a novel motion controller for the online generation of natural character locomotion that adapts to new situations such as changing user control or applying external forces. This controller ... -
Watercolor Woodblock Printing with Image Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Watercolor paintings have a unique look that mixes subtle color gradients and sophisticated diffusion patterns. This makes them immediately recognizable and gives them a unique appeal. Creating such paintings requires ... -
String Art: Towards Computational Fabrication of String Images
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we propose a novel method for the automatic computation and digital fabrication of artistic string images. String art is a technique used by artists for the creation of abstracted images which are composed ... -
Packable Springs
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Laser cutting is an appealing fabrication process due to the low cost of materials and extremely fast fabrication. However, the design space afforded by laser cutting is limited, since only flat panels can be cut. Previous ... -
Fast Penetration Volume for Rigid Bodies
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Handling collisions among a large number of bodies can be a performance bottleneck in video games and many other real-time applications. We present a new framework for detecting and resolving collisions using the penetration ... -
Efficient BVH-based Collision Detection Scheme with Ordering and Restructuring
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Bounding volume hierarchy (BVH) has been widely adopted as the acceleration structure in broad-phase collision detection. Previous state-of-the-art BVH-based collision detection approaches exploited the spatio-temporal ... -
GazeDirector: Fully Articulated Eye Gaze Redirection in Video
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present GazeDirector, a new approach for eye gaze redirection that uses model-fitting. Our method first tracks the eyes by fitting a multi-part eye region model to video frames using analysis-by-synthesis, thereby ...
