Toward Optimal Space Partitioning for Unbiased, Adaptive Free Path Sampling of Inhomogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Photo-realistic rendering of inhomogeneous participating media with light scattering in consideration is impor- tant in computer graphics, and is typically computed using Monte Carlo based methods. The key technique in ...
Interactive Indirect Illumination Using Voxel Cone Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Indirect illumination is an important element for realistic image synthesis, but its computation is expensive and highly dependent on the complexity of the scene and of the BRDF of the involved surfaces. While off-line ...
Improving Performance and Accuracy of Local PCA
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Local Principal Component Analysis (LPCA) is one of the popular techniques for dimensionality reduction and data compression of large data sets encountered in computer graphics. The LPCA algorithm is a variant of kmeans ...
A Graph-based Approach to Continuous Line Illustrations with Variable Levels of Detail
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper introduces a method for automatically generating continuous line illustrations, drawings consisting of a single line, from a given input image. Our approach begins by inferring a graph from a set of edges extracted ...
Rephotography Using Image Collections
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper proposes a novel system that 'rephotographs' a historical photograph with a collection of images. Rather than finding the accurate viewpoint of the historical photo, users only need to take a number of photographs ...
An Illustrative Visualization Framework for 3D Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Most 3D vector field visualization techniques suffer from the problem of visual clutter, and it remains a challenging task to effectively convey both directional and structural information of 3D vector fields. In this ...
Creating Fluid Animation from a Single Image using Video Database
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a method for synthesizing fluid animation from a single image, using a fluid video database. The user inputs a target painting or photograph of a fluid scene along with its alpha matte that extracts the fluid ...
Motion Deblurring from a Single Image using Circular Sensor Motion
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Image blur caused by object motion attenuates high frequency content of images, making post-capture deblurring an ill-posed problem. The recoverable frequency band quickly becomes narrower for faster object motion as high ...
Edge-Optimized À-Trous Wavelets for Local Contrast Enhancement with Robust Denoising
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper we extend the edge-avoiding à-trous wavelet transform for local contrast enhancement while avoiding common artifacts such as halos and gradient reversals. We show that this algorithm is a highly efficient and ...
Exposure Fusion for Time-Of-Flight Imaging
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This work deals with the problem of automatically choosing the correct exposure (or integration) time for timeof- flight depth image capturing. We apply methods known from high dynamic range imaging to combine depth images ...
