Modeling light scattering for virtual heritage
Diego Gutierrez, Veronica Sundstedt, Fermin Gomez, Alan Chalmers
Article No.: 8
DOI: 10.1145/1434763.1434765

Computer graphics, in particular high-fidelity rendering, make it possible to recreate cultural heritage on a computer, including a precise lighting simulation. Achieving maximum accuracy is of the highest importance when investigating how a site...

Using survival analysis on conservation metadata to benchmark treatment frequency
Jeremy Hutchings, Jonathan Ashley Smith
Article No.: 9
DOI: 10.1145/1434763.1434766

This research addresses the question of what is an acceptable period between conservation treatments. Taking the cleaning of impressionist paintings as a case study, survival analysis is carried out on metadata from conservation records for the...

Islamic geometrical patterns indexing and classification using discrete symmetry groups
Mohamed Ould Djibril, Rachid Oulad Haj Thami
Article No.: 10
DOI: 10.1145/1434763.1434767

In this article, we propose a general computational model for the extraction of symmetry features of Islamic geometrical patterns' (IGP) images. We describe IGP images using the discrete symmetry groups theory. Our model contains the three...

Exploring cultural heritage sites through space and time
R. G. Laycock, D. Drinkwater, A. M. Day
Article No.: 11
DOI: 10.1145/1434763.1434768

Traveling through a single virtual environment only tells part of the story; a particularly interesting aspect is to illustrate how an area has developed over time. This article presents a unified approach to illustrating four-dimensional data...

Semantic fitting and reconstruction
Torsten Ullrich, Volker Settgast, Dieter W. Fellner
Article No.: 12
DOI: 10.1145/1434763.1434769

The current methods to describe the shape of three-dimensional objects can be classified into two groups: methods following the composition of primitives approach and descriptions based on procedural shape representations. As a 3D...
