摘要
对粉末显微图像进行粒度分析的关键是颗粒边界的描述和面积的计算。根据数字图像的链码与图像区域边界的关系 ,采用 4链码描述图像边界 ,提出了一种基于Green公式的边界积分算法。该算法效率高 。
In size analysis of powder′s microphotograph it is the key to describe particle boundary and calculate particle area. To describe the particle boundary, the crack code is used in terms of the relation to the boundary in this paper. Based on Green formula, an algorithm of the set area is proposed in this paper. It is efficient and has been applied to the size analysis of the powder microphotograph in mineral processing.
