摘　　要：文章首先对传统Canny边缘检测算法的性能进行分析和研究,并在保持了Canny算子原有的优点的基础上,提出了一种通过改进梯度幅值计算和非极值抑制过程的插值方向的方法,不仅提高了边缘定位的精度,而且抑制了伪边缘和噪声,在实际的应用中取得了很好的边缘检测效果.实验结果证明,该算法是一种有效的边缘检测改进方法.In this paper,first,the traditional Canny edge detection algorithm＇s performance is analyzed and studied,the extremum inhibit process of interpolation method of direction was proposed by maintaining a Canny operator original merit in the foundation and improving gradient amplitude calculation,which not only improves the accuracy of edge detection,and restrains the pseudo edge and noise,in actual applications very good edge detection effect was made.The experimental results show that this algorithm is an effective method of edge detection improvement.
