| 摘 要： | 针对定量金相分析中金相图像的晶界恢复与重建以及数学形态学在图像处理中的特殊作用,从理论上证明了传统膨胀运算对图像灰度连续性的影响及影响程度与结构元素尺寸的关系,并对传统的膨胀运算的定义做了改进,据此提出了多尺度测地膨胀算法并以此恢复和重建金相图像的晶界.首先依据改进的膨胀运算对金相图像进行预处理;然后用多尺度迭代腐蚀和...

| Abstract: | According to the restoration and reconstruction of the grain boundaries in a metallographical image and the important role of mathematical morphology in image processing,the influences of traditional dilation of mathematical morphology on the gray-scale continuity of an image was demonstrated theoretically,and the relationship between the degree of influence and the sizes of structural elements was discussed.Then,an improved definition for the traditional dilation was proposed.A multi-scale geodesic dilatio... |
