An Integral Geometry Based Method for Fast Form-Factor Computation
(Blackwell Science Ltd and the Eurographics Association, 1993)
Monte Carlo techniques have been widely used in rendering algorithms for local integration. For example, to compute the contribution of a patch to the luminance of another. In the present paper we propose an algorithm based ...
Visibility Complexity of a Region in Flatland
(Eurographics Association, 2000)
The aim of this paper is to study the visibility complexity of different regions in a 2D scene. Based on mutual information, which we used in our previous work to define scene complexity, we propose two measures that ...
View-based Shape Similarity using Mutual Information Spheres
(The Eurographics Association, 2007)
We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ...
Optimal Deterministic Mixture Sampling
(The Eurographics Association, 2019)
Multiple Importance Sampling (MIS) can combine several sampling techniques preserving their advantages. For example, we can consider different Monte Carlo rendering methods generating light path samples proportionally only ...
Information-Theoretic Oracle Based on Kernel Smoothness for Hierarchical Radiosity
(Eurographics Association, 2002)
One of the main problems in the radiosity method is how to discretise the surfaces of a scene into mesh elements that allow us to accurately represent illumination. In this paper we present a robust information-theoretic ...
Multi-layered Indirect Texturing for Tree Rendering
(The Eurographics Association, 2007)
This paper presents a technique to render in real time complex trees using billboard clouds as an impostor simplification for the original polygonal tree, combined with a new texture-based representation for the foliage. ...
Conceptualizing Birkhoff's Aesthetic Measure Using Shannon Entropy and Kolmogorov Complexity
(The Eurographics Association, 2007)
In 1928, George D. Birkhoff introduced the Aesthetic Measure, defined as the ratio between order and complexity, and, in 1965, Max Bense analyzed Birkhoff s measure from an information theory point of view. In this paper, ...
Fast Visualisation and Interactive Design of Deterministic Fractals
(The Eurographics Association, 2008)
This paper describes an interactive software tool for the visualisation and the design of artistic fractal images. The software (called AttractOrAnalyst) implements a fast algorithm for the visualisation of basins of ...
Toward Auvers Period: Evolution of van Gogh's Style
(The Eurographics Association, 2010)
In this paper, we analyze the evolution of van Gogh's style toward the Auvers final period using informational measures. We will try to answer the following questions: Was van Gogh exploring new ways toward changing his ...
Benford's Law for Natural and Synthetic Images
(The Eurographics Association, 2005)
Benford's Law (also known as the First Digit Law) is well known in statistics of natural phenomena. It states that, when dealing with quantities obtained from Nature, the frequency of appearance of each digit in the first ...
