| 摘 要： | 颗粒形态分析是准确进行颗粒识别的基础.本文利用图像处理技术统计颗粒数目,标注颗粒质心,计算了颗粒的面积、周长、圆度、矩形度、伸长度和凸缺率等几何形态特征.其中,凸缺率是为描述一个连通域集合的凹陷程度提出的新概念.实验结果表明,本文的颗粒形态分析算法可以准确有效地完成颗粒形态分析.

| Abstract: | The analysis of granule configuration is the base of identifying granule. This paper proposes an algorithm based on digital image processing, which can mark the centroid,count the amount of granule and compute the geometry configuration characteristic. Generally, the geometry configuration consists of the area,perimeter, circle ratio, rectangle ratio, elongation and convex deficiency ratio. Especially, the convex deficiency ratio is a new concept for the concave degree. The experiment results show that the proposed algorithm in this paper can complete the analysis of granule configuration efficiently. |
