This work presents a tracking algorithm based on a set of naive Bayesian classifiers. We consider tracking as a classification problem and train online a set of classifiers which distinguish a target object from the background around it. Classifiers’ voting make a soft decision about class adherence for each pixel in video frame, forming a confidence map. We use the mean shift algorithm to find the nearest peak in the confidence map, with respect to the previous position of the target. The location of that peak represents the new position of the object. The temporal adaptivity of the tracker is achieved by gradual update of a target model. The results demonstrate ability of the proposed method to perform successful tracking in different environmental conditions.
