| 摘 要： | 提出了一种简单而高效的在二值图像中检测目标物体直线边界的算法．基于Freeman提出的关于数字直线的准则和数字直线的特征，得出线段元是数字直线的组成部分这一性质．基于该性质，该算法以线段元为基本单位进行直线的构造，从而能高效、准确地检测出图像中物体边界中的直线．此外，该算法还可用于检测二值图像中物体边界的拐角．

| Abstract: | This paper proposes a simple and efficient algorithm to detect line edge of objects in a binary image. Based on the criteria and characteristic of digital line suggested by Freeman, we derived that digital line is composed of sets of line segment cell. Derived from this property of line cell, in the algorithm proposed, line cells are used for connection to form line segment. It makes the algorithm very efficient and precise. This algorithm can also be used to detect corner of objects in binary images. |
