Patternista: Learning Element Style Compatibility and Spatial Composition for Ring-based Layout Decoration
(The Eurographics Association, 2016)Creating aesthetically pleasing decorations for daily objects is a task that requires deep understanding of multiple aspects of object decoration, including color, composition and element compatibility. A designer needs a ... -
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 ... -
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 ... -
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' ... -
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 ... -
Rasterizing and antialiasing vector line art in the pixel art style
(ACM, 2013)Pixel artists rasterize vector shapes by hand to minimize artifacts at low resolutions and emphasize the aesthetics of visible pixels. We describe Superpixelator, an algorithm that automates this process by rasterizing ... -

Towards effective evaluation of geometric texture synthesis algorithms
(ACM, 2013)In recent years, an increasing number of example-based Geometric Texture Synthesis (GTS) algorithms have been proposed. However, there have been few attempts to evaluate these algorithms rigorously. We are driven by this ... -
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 ... -
Texture-Aware ASCII Art Synthesis with Proportional Fonts
(The Eurographics Association, 2015)We present a fast structure-based ASCII art generation method that accepts arbitrary images (real photograph or hand-drawing) as input. Our method supports not only fixed width fonts, but also the visually more pleasant ... -
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 ... -
Semi-Automatic Digital Epigraphy from Images with Normals
(The Eurographics Association, 2015)We present a semi-automated system for converting photometric datasets (RGB images with normals) into geometry-aware non-photorealistic illustrations that obey the common conventions of epigraphy (black-and-white archaeological ... -
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 ... -
Texture-Preserving Abstraction
(The Eurographics Association, 2012)Image abstraction traditionally eliminates texture, but doing so ignores the more elegant alternative of texture indication, e.g., suggesting the presence of texture through irregular silhouettes and locally chosen details. ... -
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 ... -
Virtual Passepartouts
(The Eurographics Association, 2012)In traditional media, such as photography and painting, a cardboard sheet with a cutout (called passepartout) is frequently placed on top of an image. One of its functions is to increase the depth impression via the ... -
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 ... -
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 ... -
Pixelating Vector Line Art
(The Eurographics Association, 2012)Creating pixel art is a laborious process that requires artists to place individual pixels by hand. Although many image editors provide vector-to-raster conversions, the results produced do not meet the standards of pixel ... -
Pixelated Image Abstraction
(The Eurographics Association, 2012)We present an automatic method that can be used to abstract high resolution images into very low resolution outputs with reduced color palettes in the style of pixel art. Our method simultaneously solves for a mapping of ...
