彩色序列图像中移动目标定位与区域提取

Moving Target Location and Regions Extraction Based on Color Image Sequence

提出一种基于彩色序列图像提取移动目标区域的新方法。首先采用时态差分法进行运动目标定位,对彩色序列图像进行差分;然后通过选择阈值将彩色差分图像转化为二值图像;为了克服背景扰动和摄像头抖动,采用了对称差分算法,使得运动目标的定位更为准确。最后在对称差分的基础上,通过投影提取移动目标区域,为了消除扰动造成的影响,采用了杂块去除和区域合并方法。实验结果表明所提方法能有效快速地提取出移动目标。

A new method for locating moving targets and extracting moving object regions from image based on color image sequence is proposed. Firstly, color image sequences are differenced to locate moving targets. Then color difference images are transformed to binary images by selecting a threshold. In order to exclude the influences of camera vibration and background objects sway, symmetrical difference are adopted. Finally, projection algorithm is used to extract moving target regions from images. The method for removing impurity regions and the method for combining target regions are imported to obtain exact and continuous moving target regions. The experiment results show the method is able to locate moving target and extract moving target regions efficiently and quickly.
