【摘要】 基于内容检索方法的提出,对视频对象的处理提出了新的要求。随着MPEG-4基于内容功能的提出以及MPEG-7标准的不断推广应用,视频对象分割技术已成为视频处理领域中的研究热点。视频对象分割就是从视频序列中分割出在语义上有意义的对象。文章从构成视频对象的区域出发,介绍了阈值分割、区域生长算法等视频分割技术,并对视频分割技术中需要深入研究的问题进行了探讨。更多还原

【Abstract】 Based on content retrieval method proposing, Sets the new request to video frequency object processing. Due to the emerging of content-based functionalities in MPEG-4 and applying of MPEG-7, object-based segmentation technology, the segmenta- tion of semantically meaningful object in video sequences, becomes a popular research in video field. From shot - based to extraction of video object Planes (VOPs), video segmentation develops to extract video object (VO). From the constitution of video object region, the paper presents video segmentation technology and so on threshold value segmentation, region growth algorithm. Furthermore some existing problems worth discussing and further research are proposed.更多还原
