背景提取和水平集相结合的运动目标轮廓提取方法

提出一种基于背景提取和水平集的方法来进行运动目标的检测和轮廓提取。首先,通过一种改进的背景提取法将视频序列中的背景提取出来,然后通过结合背景差分结果和帧间差分结果检验出运动目标的运动区域,以检验出的运动区域的外接矩形为初始曲线,应用一种无需初始化的水平集的方法进行运动目标轮廓的提取。仿真实验表明,该方法能够实时有效地对运动目标轮廓进行提取。

Extraction Method of Moving Object Contour Using Background Extraction and Level Set

This paper proposes a novel method for extracting moving object contour based on background extraction and level set.First,it extracts the background using an improved method.After image binarization and morphological operations,motion region boundary is detected by a method combined background subtraction and image difference.Then using the detected motion region as the initial evolving curve,the moving object contour is extracted using a fast level set method without re-initialization.The experimental res...
