• Irregular Pebble Mosaics with Sub-Pebble Detail 

  Javid, Ali Sattari; Doyle, Lars; Mould, David (The Eurographics Association, 2019)

  Pebble mosaics convey images through an irregular tiling of rounded pebbles. Past work used relatively uniform tile sizes. We show how to create detailed representations of input photographs in a pebble mosaic style; we ...

• Stipple Removal in Extreme-tone Regions 

  Azami, Rosa; Doyle, Lars; Mould, David (The Eurographics Association, 2019)

  Conventional tone-preserving stippling struggles with extreme-tone regions. Dark regions require immense quantities of stipples, while light regions become littered with stipples that are distracting and, because of their ...

• Defining Hatching in Art 

  Philbrick, Greg; Kaplan, Craig S. (The Eurographics Association, 2019)

  We define hatching-a drawing technique-as rigorously as possible. A pure mathematical formulation or even a binary this-or-that definition is unreachable, but useful insights come from driving as close as we can. First we ...

• Aesthetics of Curvature Bases for Sketches 

  Lippincott, Keith; Hatton, Ross L.; Grimm, Cindy (The Eurographics Association, 2019)

  In this work we propose a curve approximation method that operates in the curvature domain. The curvature is represented using one of several different types of basis functions (linear, quadratic, spline, sinusoidal, ...

• Abstract Shape Synthesis From Linear Combinations of Clelia Curves 

  Putnam, Lance; Todd, Stephen; Latham, William (The Eurographics Association, 2019)

  This article outlines several families of shapes that can be produced from a linear combination of Clelia curves. We present parameters required to generate a single curve that traces out a large variety of shapes with ...

• Aesthetically-Oriented Atmospheric Scattering 

  Shen, Yang; Mallett, Ian; Shkurko, Konstantin (The Eurographics Association, 2019)

  We present Aesthetically-Oriented Atmospheric Scattering (AOAS): an experiment into the feasibility of using real-time rendering as a tool to explore sky styles. AOAS provides an interactive design environment which enables ...

• Generating Playful Palettes from Images 

  DiVerdi, Stephen; Lu, Jingwan; Echevarria, Jose; Shugrina, Maria (The Eurographics Association, 2019)

  Playful Palettes are a recent innovation in how artists can mix, explore, and choose colors in a user interface that combines the benefits of a traditional media painter's palette with non-destructive capabilities of digital ...

• Single Stroke Aerial Robot Light Painting 

  Ren, Kejia; Kry, Paul G. (The Eurographics Association, 2019)

  This paper investigates trajectory generation alternatives for creating single-stroke light paintings with a small quadrotor robot. We propose to reduce the cost of a minimum snap piecewise polynomial quadrotor trajectory ...

• Sketching and Layering Graffiti Primitives 

  Berio, Daniel; Asente, Paul; Echevarria, Jose; Leymarie, Frederic Fol (The Eurographics Association, 2019)

  We present a variant of the skeletal strokes algorithm aimed at mimicking the appearance of hand made graffiti art. It includes a unique fold-culling process that stylizes folds rather than eliminating them. We demonstrate ...

• Enhancing Neural Style Transfer using Patch-Based Synthesis 

  Texler, Ondřej; Fišer, Jakub; Lukáč, Mike; Lu, Jingwan; Shechtman, Eli; Sýkora, Daniel (The Eurographics Association, 2019)

  We present a new approach to example-based style transfer which combines neural methods with patch-based synthesis to achieve compelling stylization quality even for high-resolution imagery. We take advantage of neural ...

• Real-Time Patch-Based Stylization of Portraits Using Generative Adversarial Network 

  Futschik, David; Chai, Menglei; Cao, Chen; Ma, Chongyang; Stoliar, Aleksei; Korolev, Sergey; Tulyakov, Sergey; Kučera, Michal; Sýkora, Daniel (The Eurographics Association, 2019)

  We present a learning-based style transfer algorithm for human portraits which significantly outperforms current state-of-the-art in computational overhead while still maintaining comparable visual quality. We show how to ...

• Learning from Multi-domain Artistic Images for Arbitrary Style Transfer 

  Xu, Zheng; Wilber, Michael; Fang, Chen; Hertzmann, Aaron; Jin, Hailin (The Eurographics Association, 2019)

  We propose a fast feed-forward network for arbitrary style transfer, which can generate stylized image for previously unseen content and style image pairs. Besides the traditional content and style representation based on ...

• Video Motion Stylization by 2D Rigidification 

  Delanoy, Johanna; Bousseau, Adrien; Hertzmann, Aaron (The Eurographics Association, 2019)

  This paper introduces a video stylization method that increases the apparent rigidity of motion. Existing stylization methods often retain the 3D motion of the original video, making the result look like a 3D scene covered ...

• Non-Photorealistic Animation for Immersive Storytelling 

  Curtis, Cassidy J.; Dart, Kevin; Latzko, Theresa; Kahrs, John (The Eurographics Association, 2019)

  Immersive media such as virtual and augmented reality pose some interesting new challenges for non-photorealistic animation: we must not only balance the screen-space rules of a 2D visual style against 3D motion coherence, ...

• Frontmatter: Expressive 2019 

  Kaplan, Craig S.; Forbes, Angus; DiVerdi, Stephen (The Eurographics Association, 2019)

• Stylized Stereoscopic 3D Line Drawings from 3D Images 

  Istead, Lesley; Kaplan, Craig S. (ACM, 2018)

  Stereoscopic 3D (S3D) line drawings were introduced by Sir Charles Wheatstone in 1838. S3D line drawings persist today in various art forms, such as comic books. Stereoscopic 3D line drawings may be hand-drawn or generated ...

• Approaches for Local Artistic Control of Mobile Neural Style Transfer 

  Reimann, Max; Klingbeil, Mandy; Pasewaldt, Sebastian; Semmo, Amir; Döllner, Jürgen; Trapp, Matthias (ACM, 2018)

  This work presents enhancements to state-of-the-art adaptive neural style transfer techniques, thereby providing a generalized user interface with creativity tool support for lower-level local control to facilitate the ...

• Automatic Generation of Geological Stories from a Single Sketch 

  Garcia, Maxime; Cani, Marie-Paule; Ronfard, Rémi; Gout, Claude; Perrenoud, Christian (ACM, 2018)

  Describing the history of a terrain from a vertical geological cross-section is an important problem in geology, called geological restoration. Designing the sequential evolution of the geometry is usually done manually, ...

• An ego-altruist society 

  Cruz, Pedro M.; Cunha, André B. (ACM, 2018)

  This artwork is an artificial life simulation that shows how a society of agents flourishes with the symbiotic interactions between the egotist and altruist extremes. Egotist agents seek and absorb energy. Altruist agents ...

• ToonCap: A Layered Deformable Model for Capturing Poses From Cartoon Characters 

  Fan, Xinyi; Bermano, Amit H.; Kim, Vladimir G.; Popović, Jovan; Rusinkiewicz, Szymon (ACM, 2018)

  Characters in traditional artwork such as children's books or cartoon animations are typically drawn once, in fixed poses, with little opportunity to change the characters' appearance or re-use them in a different animation. ...
