Identification and reconstruction of bullets from multiple X-rays (2006)
Perkins, Simon, Marais, Patrick
We present a framework for the rapid detection and 3D localisation of bullets (or other compact shapes) from a sparse set of cross-sectional patient x-rays. The intention of this work is to assess a...
Proposed framework for anomalous change detection (2006)
For the anomalous change detection problem, you have a pair of images, taken of the same scene, but at different times and typically under different viewing conditions. You are looking for...

Grafting: Fast, incremental feature selection by gradient descent in function space (2003)
Simon Perkins, Kevin Lacker, James Theiler, Isabelle Guyon, André Elisseeff
We present a novel and flexible approach to the problem of feature selection, called grafting. Rather than considering feature selection as separate from learning, grafting treats the selection of...
