摘要
给出了二值数字图像区域外接矩形的一种获取算法。对于图像方形点阵中的8近邻的情形,建立了标定区域边界的基本图,通过自动标定区域边界取得其像素点集,最后给出了获取图像区域最小外接矩形的实现方法。
In this paper,a new kind of algorithm for obtaining minimum exterior rectangle of digital image region is presented. It sets up the basic graphs of image labeling for 8-site neighborhood digital images, based on basic graphs of image labeling, people can gain pixel pipointset of region boundary directly by automatic labeling. Finally it provides the implementaion of obtaining minimum exterior rectangle of digital image region.
