线条化的边界检测

Lined edge detection

在分析边界线特征的基础上,指出边界线上的点除了具有分隔亮度不同的两个区域这一基本特征之外,还具有方向性和连续性,并据此提出了一种检测出宽度为1的边界线的方法.实验表明,运用该方法得到的边界线能更好地定位物体的边缘.

Based on the analysis of features of lined edge,it is pointed out that edge points divide two areas with different intensity,and are directional and continuous.Then an algorithem is given out to detect edge line having width of 1.Experimental results show that lines obtained from the algorithm fit the object edge better.
