研究了一种目标物体边缘参数的提取算法．霍夫变换是图像处理和计算机视觉过程中常用的一种方法，用来在图像中提取目标边缘．文中提出一种新的算法以提高霍夫变换的边缘参数的检测能力，并用迭代中值滤波来完成直线边缘的定位．计算机仿真结果显示这种算法的有效性．

An object edge parameter extraction algorithm is provided. Hongh transform is a general method used in image processing and computer vision processes to extract the edge characters of the objects in images. In this paper, a new algorithm is derived to improve the edge parameter detection ability of the Hough transform and the iterated median filter is used to complete the line edge positioning. The computer simulation results show the effectiveness of this algorithm.
