说明：  文中提出了一种新的二值图象边界提取算法。通过分析边界象素的特征，归纳出一个边界象素提取算子，该算子最多 只需要计算象素的4邻域象素，运算量小，速度快，运用他能直接提取出二值图象的边界象素，得到单象素宽的边界。实验 结果表明．该算法要优于传统的二值图象边界提取算法，实用性强。
(In this paper, a new binary image boundary extraction algorithm. By analyzing the characteristics of the boundary pixels to formulate a boundary pixel extraction operator, the operator need only calculate up to 4 pixels neighborhood pixels, is efficient, fast, he can direct the use of binary images are extracted as the boundary pixel, are single-pixel wide border. The results show that. The algorithm is superior to the traditional binary image edge detection algorithm, and practical.)
