摘　　要：利用数学形态学简单准确和便于捕捉图形特征的特点,提出了一种提取圆形目标并定位图像方法。先用形态学开运算去除较小团块,再通过形态学边缘提取算法找出图像中物体边缘,通过圆形的判别标准,提取图像中圆形目标,并定位了圆心的位置。实验表明这是一种有效的提取圆形目标的方法。是实现多种特征定位的有效尝试。In this paper, the recognition and localization of object base on mathematical morphology are discussed. A new algorithm which can extract the circle object and locate the center of circle in an image is proposed . Firstly, small blocks are removed by open operation. Then edge is detected through morphology edge operations. The circle objects are detected through the criterion of circle object. And the center of the circles are located. The experiments show that the algorithms for extracting circle object base on mathematical morphology are simple and effective.
