摘要
Sprite图像是视频对象VO(Video Object)在一端图像序列中所有可见部分的组合,是MPEG-4提出的重要概念之一。根据MPEG-4校验模型,利用全局运动估计技术和图像镶嵌技术,给出了一种动态Sprite的生成方法,针对视频序列的实际处理结果表明该算法是成功的。
A Sprite which is an image composed of the pixels belonging to a visible video object throughout a video segment is an important concept proposed by MPEG-4.This paper, according to verification models(VMs) of MPEG-4, presents a online Sprite generation technology by using global motion estimation technology and image mosaic technology. The results of processing video sequence demonstrate the performance of algorithm.
