| 摘 要： | 金相图象特征信息提取是进行金相分析的关键.本文在分析金相图象的区域和边缘(晶界)二类特征信息基础上,指出采用基于熵概念的图象阈值化技术可实现区域特征提取.用微分算子实现边缘(晶界)提取后,采用适合晶界及网状结构的滤波方法进行滤波,从而实现边缘(晶界)的准确提取,并通过实验验证了上述方法的有效性.

| Abstract: | The extracting features of metallography is the key to metallographic analysis. On the basis of analyzing area and edgr (grain boundary)features of metallography, this paper indicates: image threshoiding using entropycan extract area feature; as edge is extracted by differential operator, noise is filt-ed by a new method suitable for grain boundare and net-structure. The experi-mental results show the efficiency of the method. |
