Hybrid methods of fuzzy clustering and particle swarm optimization (PSO) are important techniques for image segmentation. The spatial credibilistic clustering (SCC) shows better performance than traditional fuzzy clustering, because of the “typicality” represented by credibility memberships degree is much more accurate than the “sharing” represented by probability membership degree to characterize...
A program to adaptively generate equivalent wire-grid structures for electromagnetic simulation of two-dimensional structures has been developed. The main purpose of this program is to simulate planar microstrip-patch antenna designs, using the numerical electromagnetics code in collaboration with a genetic algorithm (GA). In order to demonstrate how this program operates in meshing planar structures,...
