Active Strokes: Coherent Line Stylization for Animated 3D Models
(The Eurographics Association, 2012)This paper presents a method for creating coherently animated line drawings that include strong abstraction and stylization effects. These effects are achieved with active strokes: 2D contours that approximate and track ... -
Art-directed Watercolor Rendered Animation
(The Eurographics Association, 2016)This paper presents a system to render 3D animated geometry as watercolor painted animation with art-directed control. Our approach focuses on letting the end user paint the influence of the modeled watercolor effects in ... -
Automatic Texture Guided Color Transfer and Colorization
(The Eurographics Association, 2016)This paper targets two related color manipulation problems: Color transfer for modifying an image's colors and colorization for adding colors to a grayscale image. Automatic methods for these two applications propose to ... -
A Benchmark Image Set for Evaluating Stylization
(The Eurographics Association, 2016)The non-photorealistic rendering community has had difficulty evaluating its research results. Other areas of computer graphics, and related disciplines such as computer vision, have made progress by comparing algorithms' ... -
Benchmarking Non-Photorealistic Rendering of Portraits
(Association for Computing Machinery, Inc (ACM), 2017)We present a set of images for helping NPR practitioners evaluate their image-based portrait stylisation algorithms. Using a standard set both facilitates comparisons with other methods and helps ensure that presented ... -
Characterizing User Behavior for Speech and Sketch-based Video Retrieval Interfaces
(Association for Computing Machinery, Inc (ACM), 2017)From a user interaction perspective, speech and sketching make a good couple for describing motion. Speech allows easy speci cation of content, events and relationships, while sketching brings in spatial expressiveness. ... -
Combining Sketch and Tone for Pencil Drawing Production
(The Eurographics Association, 2012)We propose a new system to produce pencil drawing from natural images. The results contain various natural strokes and patterns, and are structurally representative. They are accomplished by novelly combining the tone and ... -
Consistent Stylization and Painterly Rendering of Stereoscopic 3D Images
(The Eurographics Association, 2012)We present a method for stylizing stereoscopic 3D images that guarantees consistency between the left and right views. Our method decomposes the left and right views of an input image into discretized disparity layers and ... -
Data-Driven Iconification
(The Eurographics Association, 2016)Pictograms (icons) are ubiquitous in visual communication, but creating the best icon is not easy: users may wish to see a variety of possibilities before settling on a final form, and they might lack the ability to draw ... -
Depth-aware Neural Style Transfer
(Association for Computing Machinery, Inc (ACM), 2017)Neural style transfer has recently received signi cant a ention and demonstrated amazing results. An e cient solution proposed by Johnson et al. trains feed-forward convolutional neural networks by de ning and optimizing ... -
Drawing Characteristics for Reproducing Traditional Hand-Made Stippling
(The Eurographics Association, 2015)We contribute an in-depth analysis of the characteristics of traditional stippling and relate these to common practices in NPAR stippling techniques as well as to the abilities and limitations of existing printing and ... -
Edge- and substrate-based effects for watercolor stylization
(Association for Computing Machinery, Inc (ACM), 2017)We investigate characteristic edge- and substrate-based effects for watercolor stylization. These two fundamental elements of painted art play a significant role in traditional watercolors and highly influence the pigment's ... -
ELASTIFACE: Matching and Blending Textured Faces
(ACM, 2013)In this paper we present ELASTIFACE, a simple and versatile method for establishing correspondence between textured face models, either for the construction of a blend-shape facial rig or for the exploration of new characters ... -
Example-Based Brushes for Coherent Stylized Renderings
(Association for Computing Machinery, Inc (ACM), 2017)Painterly stylization is the cornerstone of non-photorealistic render- ing. Inspired by the versatility of paint as a physical medium, exist- ing methods target intuitive interfaces that mimic physical brushes, providing ... -

A generic framework for the structured abstraction of images
(Association for Computing Machinery, Inc (ACM), 2017)Structural properties are important clues for non-photorealistic representations of digital images. erefore, image analysis tools have been intensively used either to produce stroke-based render- ings or to yield abstractions ... -
Hybrid-Space Localized Stylization Method for View-Dependent Lines Extracted from 3D Models
(The Eurographics Association, 2015)We propose a localized stylization method that combines object-space and image-space techniques to locally styl- ize view-dependent lines extracted from 3D models. In the input phase, the user can customize a style and ... -
Interactive NPAR: What Type of Tools Should We Create?
(The Eurographics Association, 2016)I argue that we need to increase our consideration of the interaction that is possible and/or needed for the NPAR algorithms we develop. Depending on the application domain of a given algorithmic contribution, different ... -
Map Style Formalization: Rendering Techniques Extension for Cartography
(The Eurographics Association, 2016)Cartographic design requires controllable methods and tools to produce maps that are adapted to users' needs and preferences. The formalized rules and constraints for cartographic representation come mainly from the ... -
The Markov Pen: Online Synthesis of Free-Hand Drawing Styles
(The Eurographics Association, 2015)Learning expressive curve styles from example is crucial for interactive or computer-based narrative illustrations. We propose a method for online synthesis of free-hand drawing styles along arbitrary base paths by means ...
