Abstract

This paper presents an approach for a real-time region-based motion segmentation and tracking using an adaptive thresholding and k-means clustering in a scene, with focus on a video monitoring system. In order to reduce the computational load to the motion segmentation, the presented approach is based on the variation regions application of a weighted k-means clustering algorithm, followed by a motion-based region merging procedure. To indicate motion mask regions in a scene, instead of determining the threshold value manually, we use an adaptive thresholding method to automatically choose the threshold value. To image segment, the weighted k-means clustering algorithm is applied only on the motion mask regions of the current frame. In this way we do not to process the whole image so that the computation time is reduced. The presented method is able to deal with occlusion problems. Results show the validity of the presented method.
