With the development of intelligent algorithm, GA and PSO have become the hot spot for the study on multi-objective optimization in recently years. Information sharing is the core of PSO algorithm, Comparing with GA, PSO algorithm has less variables to adjust and is easy to achieve, so it is widely used in engineering. This paper focus on the comparation on several PSO algorithm and introduce a kind...
A new method for image segmentation is presented. It combines the nonsubsampled contourlet transform (NSCT) with the marker-controlled watershed algorithm to control over-segmentation and therefore achieving better segmentation. The NSCT is employed to denoise the image and enhance the edges in multiple resolutions, and the image gradient is estimated at each scale. The marker-controlled watershed...
