Multilevel Thresholding for Image Segmentation using Particle Swarm Optimization with Chaotic Inertia Weight

In this paper, the multilevel image thresholding methods based on the particle swarm optimization algorithm and different chaotic inertia weight strategies are considered. The performance of each chaotic inertia weight strategy is evaluated using a set of standard test images. Different numbers of image classes are considered. In addition, the paper also considers the multilevel thresholding performance based on commonly employed linear decreasing inertia weight and random inertia weight. All considered multilevel thresholding methods are based on Kapur’s entropy. The experimental results demonstrate that the particle swarm optimization with chaotic inertia weight can be successfully used for multilevel image thresholding.
