为适应MPEG-4 基于对象的应用,提出一种基于视频对象的区域分割算法。在视频对象的指导下,利用均值漂移进行分割,性能
比传统均值漂移算法在计算时间、占用内存等方面均有提高,适用于运算速度要求高和处理器资源有限的情况。将分割结果应用于区域指
导的图像插值,能保证较快的处理速度和兴趣区域较好的图像质量。实验结果证明了该方法的有效性。

【Abstract】In order to adapt to the requirement of MPEG-4 object-oriented operations, Region Segmentation based on Video Object (RSVO) is
proposed. The mean shift process can be performed in the area of video object. RSVO can speed up calculating time and save memory compared
with traditional mean shift method, and it is suitable for situation where high speed is needed and memory resource is restricted. In order to save
calculating time while guarantee high quality for the region of interest, results of RSVO are used to area-directed image interpolation. Experimental
results show the validity of the method.
【Key words】region segmentation; mean shift; image interpolation
