In this article, we present a new algorithm to track a moving object based on fuzzy histogram information employing a particle filter algorithm. Recently a particle filter has been proven very successful for nonlinear and nonGaussian estimation problems. It approximates a posterior probability density of the state, such as the object position, by using samples which are called particles. Also, a fuzzy method of color and edge histograms is used. For likelihood, we consider the similarity between the fuzzy histograms of the tracked object and the region around the position of each particle with a Stochastic feature Fusion Scheme. The Bhattacharya distance is used to measure this similarity. The mean state of the particles is treated as the estimated position of the object. The experiment shows that the proposed method has strong tracking robustness and can effectively solve this problem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
