Color image edge detection based on quantity of color information and implementation on the GPU. (2011)
Presentation / Conference Contribution
Zhao, J., Xiang, Y., Dawson, L., & Stewart, I. (2011, December). Color image edge detection based on quantity of color information and implementation on the GPU. Presented at 23rd IASTED International Conference on Parallel and Distributed Computing and Systems, PDCS'11., Dallas, USA

In this paper, we present a new method for quantifying color information so as to detect edges in color images. Our method uses the volume of a pixel in the HSI color space, allied with noise reduction, thresholding and edge thinning. We implement ou...

On the approximation complexity hierarchy. (2011)
Presentation / Conference Contribution
Bordewich, M. (2010, September). On the approximation complexity hierarchy. Presented at 8th International Workshop on International Workshop on Approximation and Online Algorithms, WAOA 2010, Liverpool

This paper presents an extension of Ladner’s Theorem to the approximation complexity hierarchy. In 1975 Ladner proved that if P≠NP, then there exists an incomplete problem A which is neither in P nor NP-complete. Here we show that if RP≠NP, then ther...

Wide field adaptive optics microscopy using both closed loop correction and image sharpness optimization (2011)
Presentation / Conference Contribution
Bourgenot, C., Love, G. D., Saunter, C. D., & Girkin, J. M. (2011, July). Wide field adaptive optics microscopy using both closed loop correction and image sharpness optimization. Presented at Imaging and Applied Optics, Toronto, Canada

We report on results from a wide field microscope fitted with adaptive optics. We describe results based on both image optimization (wavefront sensorless adaptive optics) and full closed loop correction.

Hamiltonian cycles through prescribed edges in k-ary n-cubes. (2011)
Presentation / Conference Contribution
Stewart, I. (2011, December). Hamiltonian cycles through prescribed edges in k-ary n-cubes. Presented at 5th Annual International Conference on Combinatorial Optimization and Applications, COCOA'11., Zhangjiajie, China

We prove that if P is a set of at most 2n − 1 edges in a k-ary n-cube, where k ≥ 4 and n ≥ 2, then there is a Hamiltonian cycle on which every edge of P lies if, and only if, the subgraph of the k-ary n-cube induced by the edges of P is a vertex-disj...
