摘 要: 提出了一种从摄像头获取的彩色图像中准确地检测出运动目标并进行实时跟踪的算法。 首先将采集
到的彩色视频图像序列转化为灰度图像, 研究了几种图像锐化方法并进行了比较。 然后进行帧间差分和阈值
分割, 成功分离出运动目标。 最后采用投影法得到运动目标的大小及位置。 实验结果表明, 提出的运动目标
检测与跟踪方法简单、 有效、 实时性高。

Abstrꢀct: An algorithm of detecting and tracking moving target in color images which were captured by camera was
proposed. Firstly, a series of color images were changed into gray images and several kinds of image-sharpening
methods were studied and compared. Secondly, the video sequences were differentiated and threshold segmentation
was done in order to separate the moving target from the background. At last, the size and position of the moving
target were acquired by projection method. The experimental results showed that the method of moving target detect-
ing and tracking was simpleꢁ effective and high real time.
