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...

Game-On-Demand: An Online Game Engine based on Geometry Streaming (2011)
Journal Article
Li, F., Lau, R., Kilis, D., & Li, L. (2011). Game-On-Demand: An Online Game Engine based on Geometry Streaming. ACM Transactions on Multimedia Computing, Communications and Applications, 7(3), Article 19. https://doi.org/10.1145/2000486.2000493

In recent years, online gaming is becoming very popular. In contrast to standalone games, online games tend to be large-scale and typically support interactions among users. However, due to the high network latency of the Internet, smooth interaction... Read More about Game-On-Demand: An Online Game Engine based on Geometry Streaming.

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...
