A novel moving objects segmentation method is proposed in this paper.A modified three dimensional recursive search (3DRS) algorithm is used in order to obtain motion information accurately.A motion feature descriptor (MFD) is designed to describe motion feature of each block in a picture based on motion intensity,motion in occlusion areas,and motion correlation among neighbouring blocks.Then,a fuzzy C-means clustering algorithm (FCM) is implemented based on those MFDs so as to segment moving objects.Moreover,a new parameter named as gathering degree is used to distinguish foreground moving objects and background motion.Experimental results demonstrate the effectiveness of the proposed method.
