New Algorithm for Extracting and Tracking Moving Object in Object-Based Video Coding
Zhu Zhong · Dianzi xuebao · 2003
Fast and automatic segmentation and tracking of video object is a key technology in object based video coding.A algorithm for extracting and tracking moving object is proposed.First,a binary motion image is achieved based on high order statistics detection and motion information of multiple frames.Then,an improved watershed algorithm is used to segment motion region and its surrounding areas.Thus the moving object with fine edges can be extracted with the spatial and temporal segmented results.Finally,a new algorithm is proposed to efficiently track moving object.Experimental results show that the proposed algorithm is efficient.
