Aesthetic Placement of Points Using Generalized Lloyd Relaxation
(The Eurographics Association, 2009)In this paper we describe a computational method for producing aesthetically pleasing distributions of disks on a canvas. The positions of the disks are initially given at random and are moved into interesting configurations ... -
Distinctive Parameters of Expressive Motion
(The Eurographics Association, 2009)Recent work has shown the potential of basic perceptual properties of motion for notification, association and visual search. Yet evidence from fields as diverse as perceptual science, social psychology and the performing ... -
Aesthetic Appraisal of Art - from Eye Movements to Computers
(The Eurographics Association, 2009)By looking at a work of art, an observer enters into a dialogue. In this work, we attempt to analyze this dialogue with both behavioral and computational tools. In two experiments, observers were asked to look at a large ... -
Contrast Brushes: Interactive Image Enhancement by Direct Manipulation
(The Eurographics Association, 2009)We implement contrast brushes, an interactive method for directly brushing contrast adjustments onto an image. The adjustments are performed by a histogram warping approach that implements tone mapping using piecewisedefined, ... -
Automated Landscape Painting in the Style of Bob Ross
(The Eurographics Association, 2009)We present a system that can generate convincing synthetic landscape paintings with no user intervention whatsoever, nor any information about 3D geometry or lighting. The system is based on a direct implementation of ... -
Adding Lighting and Viewing Effects to Digital Images
(The Eurographics Association, 2009)Real paintings are not truly flat but change subtly with variations in viewing direction. The pigments and painting layers also interact with the lighting environment, producing changes that range from subtle to quite ... -
Movie Posters from Video by Example
(The Eurographics Association, 2009)We present the first method for the generation of posters directly from video, borrowing the layout and composition from existing poster exemplars as a guide. Our system analyzes a given poster by determining face locations ... -
ARTcams: Attributed Rational Tensor Cameras
(The Eurographics Association, 2009)Non-linear camera models are playing an increasingly important role in computer graphics, especially in image based rendering and non-photorealistic rendering. We introduce ARTcams as simple non-linear cameras, which are ... -
Consistent Scene Illumination using a Chromatic Flash
(The Eurographics Association, 2009)Flash photography is commonly used in low-light conditions to prevent noise and blurring artifacts. However, flash photography commonly leads to a mismatch between scene illumination and flash illumination, due to the ... -
CubeCam: A Screen-space Camera Manipulation Tool
(The Eurographics Association, 2009)We present CubeCam, an image-space camera manipulation widget that uses a projected cube to both visualize the relationship of the camera to the scene and as an interaction tool to change that camera. The cube geometry ... -
Image Statistics for Clustering Paintings According to their Visual Appearance
(The Eurographics Association, 2009)Untrained observers readily cluster paintings from different art periods into distinct groups according to their overall visual appearance or 'look' [WCF08]. These clusters are typically influenced by both the content of ... -
Comparing the Readability of Graph Layouts using Eyetracking and Task-oriented Analysis
(The Eurographics Association, 2009)In this paper we present the results of a user study comparing the readability of force-directed, orthogonal, and hierarchical graph layouts. To this end we identified prototypical tasks which are solved using visual ... -
Style Nodes and Repolygonization for Hierarchical Tree-Based Implicit Surface Modelling
(The Eurographics Association, 2009)In this paper we present an extension to a hierarchical tree based implicit surface modelling system that includes interactively controlling style and appearance, and also creating a more accurate curvature based polygonal ... -
Automatic Views of Natural Scenes
(The Eurographics Association, 2009)Automatic generation of well-composed and purposeful images is useful in a variety of computer graphics applications. In this work, we explore a set of criteria based on utility, perception, and aesthetics applicable to ... -
Controlling Color Regions of Leaves with Painting Techniques for Landscape Arts
(The Eurographics Association, 2009)In this paper, we propose a non-photorealistic rendering (NPR) framework for creating landscape art in traditional animation. The proposed method is based on painting techniques for landscape arts, which enables a user ... -
A Painterly Rendering Based on Stroke Profile and Database
(The Eurographics Association, 2009)We present a method for producing painting-like images composed of predefined brush strokes. Our proposed method is based on image retrieval method and uses a stroke database. The stroke database consists of transformed ... -
Generalized Descriptions for the Procedural Modeling of Ancient East Asian Buildings
(The Eurographics Association, 2009)Many ancient East Asian buildings are noted for their immense beauty and intricate design. We introduce a graphics modeling library based on a generalized procedural description we formulated to describe East Asian ... -
Magnetic Curves: Curvature-Controlled Aesthetic Curves Using Magnetic Fields
(The Eurographics Association, 2009)We describe 'magnetic curves', a particle-tracing method that creates curves with constantly changing curvature. It is well known that charged particles in a constant magnetic field trace out circular or helical trajectories. ...
