| 摘 要： | 基于方向导数序列的概念提出一种新的边缘直线检测算法.在检测过程中,将边缘图像视为三维空间的曲面,对各个边缘点求各个方向的方向导数序列,然后由方向导数序列的取值判断确定出直线段.通过分析和编程试验证明了其算法对直线段的检测有效.

| Abstract: | A novel edge debection method is proposed to detect edge line from images.It is based on the directional derivative seguence which we propose.The disectional derivative in erery one of the edge point is calculated.By judging the numerical value of the seguence of directional derivative,the line is determined.Through analysis and programming test,the novel edge line detection method is effective. |
