Approximating a full Bidirectional Reflectance Distribution Function from a slice: Creating a BRDF trough solids of revolution

Bidirectional Reflectance Distribution Functions, BRDFs, describe the reflectance of light on a ma-terial, and are widely used in computer graphics to render materials. Acquiring a full measured BRDF can be costly and time consuming, so this research aims to answer the question ”How can we approx-imate a full BRDF from a single slice (in-plane...

Colour changes in Girl with a Pearl Earring

The goal of this project was to simulate the colour change over time of Girl with a Pearl Earring from Johannes Vermeer. Using art history knowledge and computational methods this was proven to be possible. The combination of these methods is unique and promising.<br/> <br/>As a first for the Girl, the paints that Vermeer used have been...

Performance evaluation of the CWI BRDF-fitting method under cloud-contaminated conditions: A numerical experiment using PROSAIL

Remote retrieval of Normalized Difference Vegetation Index (NDVI) over the Earth’s surface is a critical component of monitoring the surface processes of our planet. NDVI is a widely used and useful indicator of vegetation health and quantity ­ however its retrieval using satellite data is hindered by the frequent presence of clouds in the Earth...

Investigation of the Effect of the Green Glaze Layer in the Background of Girl with a Pearl Earring by Johannes Vermeer: An Approach using Optical Properties of Paints and Rendering Technique

A novel combination of analytical techniques for measuring optical properties of glaze and paint as input for computer modelling is used to investigate the influence of the green glaze layer present on top of the black underpainting in the background of Girl with a Pearl Earring. The absorption spectra of paint layers from paint reconstructions...
