为了快速准确地提取运动目标轮廓,提出了一种基于帧差法和水平集相结合的运动目标轮廓提取方法。该方法首先采用相邻帧差法确定运动目标位置,然后用一种改进型水平集的方法进行目标轮廓提取。实验结果表明,该方法均适应于刚体或非刚体目标在运动中的自由变化,能准确地提取运动目标轮廓。

In order to extract the contours of moving targets precisely, a contour extraction method based on frame difference and level set is proposed in this paper. The position of the moving target is determined firstly using the frame-difference method, followed by the modified level set method which can precisely extract the contours of the moving targets. Experimental results show that the method can accurately extract the contours of moving targets in the situation of the rigid and non-rigid shape change.
