Analysis and Visualization of Maps Between Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper we propose a method for analysing and visualizing individual maps between shapes, or collections of such maps. Our method is based on isolating and highlighting areas where the maps induce significant distortion ...
Real‐Time Defocus Rendering With Level of Detail and Sub‐Sample Blur
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This paper presents a GPU‐based rendering algorithm for real‐time defocus blur effects, which significantly improves the accumulation buffering. The algorithm combines three distinctive techniques: (1) adaptive discrete ...
Robust Fitting on Poorly Sampled Data for Surface Light Field Rendering and Image Relighting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Two‐dimensional (2D) parametric colour functions are widely used in Image‐Based Rendering and Image Relighting. They make it possible to express the colour of a point depending on a continuous directional parameter: the ...
Dynamic Comics for Hierarchical Abstraction of 3D Animation Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Image storyboards of films and videos are useful for quick browsing and automatic video processing. A common approach for producing image storyboards is to display a set of selected key-frames in temporal order, which has ...
Interactive Learning for Point-Cloud Motion Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Segmenting a moving foreground (fg) from its background (bg) is a fundamental step in many Machine Vision and Computer Graphics applications. Nevertheless, hardly any attempts have been made to tackle this problem in dynamic ...
Stroke-guided Image Synthesis for Skeletal Structure Editing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Creating variations of an image object is an important task, which usually requires manipulating the skeletal structure of the object. However, most existing methods (such as image deformation) only allow for stretching ...
Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ...
Learning to Predict Localized Distortions in Rendered Images
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this work, we present an analysis of feature descriptors for objective image quality assessment. We explore a large space of possible features including components of existing image quality metrics as well as many ...
Efficient Shadow Removal Using Subregion Matching Illumination Transfer
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This paper proposes a new shadow removal approach for input single natural image by using subregion matching illumination transfer. We first propose an effective and automatic shadow detection algorithm incorporating global ...
An Efficient Algorithm for Determining an Aesthetic Shape Connecting Unorganized 2D Points
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present anefficient algorithm for determining an aesthetically pleasing shape boundary connecting all the points in a given unorganized set of 2D points, with no other information than point coordinates. By posing shape ...
