Clustering, also known as cluster analysis, is a learning problem that occurs without the intervention of human. This technique frequently used very efficiently in data analysis to observe and identify interesting, useful, or desirable patterns data. The clustering operates by dividing involved into similar objects based on their identified properties. process results formation groups, each for...

Traditional mean-shift tracking algorithm use pre-defined tracking feature. Its trends to lead tracking failure in the complex background scenes and fast-changing background scenes. In this paper, an improved mean-shift tracking algorithm using Particle swarm optimization (PSO) based adaptive feature selection is presented to improve the tracking performance. We assume that the features with be...
