摘要： 分析目前应用于背景提取的各类聚类方法的原理和存在的问题，提出一种基于自适应在线聚类的背景提取方法。通过使用自适应动态改变的聚类阈值对视频进行在线聚类，无须设定任何参数即能自适应地提取出背景图像。实验结果表明，该方法具有较好的自适应性，能够提取出较优的背景图像，对于各种视频具有较好的鲁棒性。

Abstract: By analyzing the principles of various clustering methods and existing problems when current clustering methods are used in background extraction, this paper proposes a background extraction method based on adaptive on-line clustering. This method adopts adaptively dynamic thresholds to do on-line clustering on video to adaptively extract background images from a variety of videos without setting any parameters. Experimental results show that this method has a good adaptability, and is capable of extracting excellent background image, and has good robustness for various videos.

Key words: background extraction, K-Means clustering, on-line clustering
