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 ... -
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 ... -
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 ... -

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 taxonomy of motion applications in data visualization
(Association for Computing Machinery, Inc (ACM), 2017)We propose a new taxonomy that explains the roles of motion in data visualization, focusing especially on their communicative aspects. Our taxonomy clarifies the main axis in how visualization designers can employ motion ... -
Sketch and Shade : An interactive assistant for sketching and shading
(Association for Computing Machinery, Inc (ACM), 2017)We present a drawing assistant for sketching and for assisting users in shading a hand drawn sketch. The augmented reality based system uses a sketch made by a professional and uses it to help inexperienced users to do ... -
Whole-Cloth Quilting Patterns from Photographs
(Association for Computing Machinery, Inc (ACM), 2017)Whole-cloth quilts are decorative and functional artifacts made of plain cloth embellished with complicated stitching patterns. We describe a method that can automatically create a sewing pattern for a whole-cloth quilt ... -
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 ... -
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. ... -
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 ... -
Modeling Go: A mobile sketch-based modeling system for extracting objects
(Association for Computing Machinery, Inc (ACM), 2017)This article presents an easy to use mobile application which allows users to create 3D digital copies of their interested objects anywhere and anytime. An advanced 3-sweep modeling technique is developed to construct 3D ... -
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 ... -
Quantifying Visual Abstraction ality for Stipple Drawings
(Association for Computing Machinery, Inc (ACM), 2017)We investigate how the perceived abstraction quality of stipple illustrations is related to the number of points used to create them. Since it is di cult to nd objective functions that quantify the visual quality of such ... -
Neural Style Transfer: A Paradigm Shift for Image-based Artistic Rendering?
(Association for Computing Machinery, Inc (ACM), 2017)In this meta paper we discussimage-based artistic rendering (IB-AR)based onneural style transfer(NST) and argue, while NST may represent a paradigm shift for IB-AR, that it also has to evolve as an interactive tool that ... -
Mixed Illumination Analysis in Single Image for Interactive Color Grading
(Association for Computing Machinery, Inc (ACM), 2017)Colorists often use keying or rotoscoping tools to access and edit particular colors or parts of the scene. Although necessary, this is a time-consuming and potentially imprecise process, as it is not possible to fully ... -
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 ... -
Real-Time Panorama Maps
(Association for Computing Machinery, Inc (ACM), 2017)Panorama maps are stylized paintings of terrain often seen at tourist destinations. They are difficult to create since they are both artistic and grounded in real geographic data. In this paper we present techniques for ...
