Harmony search algorithm (HS) is a meta-heuristic algorithm which is inspired by a process involving musical improvisation. It is a stochastic optimization technique, which is similar to genetic algorithms (GAs) and particle swarm optimizers (PSOs). And it has been widely applied in order to solve many complex optimization problems, including continuous and discrete problems, such as structure design,...
According to the threat view sheds space modeling of underwater vehicle, the terrain visibility analysis method based on the acoustic line is proposed in this paper. It considered the ray model as a visibility analysis model for solving the inadaptability of traditional land ray while using under the water, and deduced the formulas to calculate acoustic ray. From the simulation results, it can be...
Reefs Extraction from satellite remote sensing images is used widely in maritime safety, marine surveying and marine military. Based on analyzing and processing IKONOS satellite remote sensing data, a reefs extraction algorithm is proposed in this paper, in which principal components analysis transformation is combined with edge enhancement. The principal component analysis transformation is applied...
