A Vision-Based Location System using Fiducials
(The Eurographics Association, 2003)
A system for vision-based ego location using 'targets' or 'fiducials' is described. The system is robust and operates on commodity hardware in real time. The accuracy of the system is assessed and found to be good enough ...
An Eigenvector Method for Surface Recovery
(The Eurographics Association, 2003)
In this paper we explore how spectral methods for graph seriation can be used to develop a new shape-fromshading algorithm. We characterise the field of surface normals using a transition matrix whose elements are computed ...
Lambertian Correction for Rough and Specular Surfaces
(The Eurographics Association, 2003)
This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...
