Abstract: Comparing the difference of head-shoulder video sequence segmentation,a new method,based on the maximal gradient region edge clustering,is proposed.Experimental results obtained on some typical MPEG-4 sequences are shown,in order to illustrate the segmentation algorithm performance.

摘要: 在充分考虑图像特性的基础上,针对可视电话、视频电视会议等领域经常出现的视频头肩序列图像,提出了一种基于最大梯度淹没区域边缘的聚类方法进行分割。由于只是对边缘附近的少量像素进行计算,因此可以提高分割速度。实验结果表明,利用该算法能够较精确地快速分割出视频对象。
