中文摘要：

针对现有的目标轮廓提取算法存在的问题,提出了一种结合背景边缘抑制和GVF Snake的运动目标轮廓提取方法.该方法首先改进了基于背景减的背景边缘抑制方法,然后将其与GVF Snake方法相结合,提取运动目标轮廓.实验结果表明该方法能准确提取出完整的运动目标轮廓.

英文摘要：

A new algorithm was proposed to extract the contour of the locomotory target, aiming to improve the performance of the current algorithms. It combined background edge eliminating method and GVF Snake. The background edge eliminating method based on background subtraction was improved first and then combined with GVF Snake to extract the locomotory target contour. Experimental results show that this method can exactly extract the whole target contour.
