Journal Article
An overview of genetic algorithms: Part 1, fundamentals
TL;DR: Genetic Algorithms (GAs) are adaptive methods which may be used to solve search and optimisation problems based on the genetic processes of biological organisms, which simulate those processes in natural populations which are essential to evolution.
Proceedings ArticleDOI
Projective image restoration using sparsity regularization
TL;DR: This paper presents a method of image restoration for projective ground images which lie on a projection orthogonal to the camera axis and proposes instant estimation of a blur kernel arising from the projective transform and the subsequent interpolation of sparse data.
Journal ArticleDOI
Pixel- and region-based image fusion with complex wavelets
TL;DR: A novel region-based image fusion method which facilitates increased flexibility with the definition of a variety of fusion rules and for regions with certain properties to be attenuated or accentuated is compared.
Journal ArticleDOI
A sequential niche technique for multimodal function optimization
TL;DR: An algorithm based on a traditional genetic algorithm that involves iterating the GA but uses knowledge gained during one iteration to avoid re-searching, on subsequent iterations, regions of problem space where solutions have already been found.
Journal ArticleDOI
A comparison of the HIPERLAN/2 and IEEE 802.11a wireless LAN standards
Angela Doufexi,Simon Armour,M.R.G. Butler,Andrew R Nix,David Bull,JP McGeehan,Peter Karlsson +6 more
TL;DR: An overview of the HIPERLAN/2 and 802.11a standards is presented together with software simulated physical layer performance results for each of the defined transmission modes.
