| 摘 要： | 根据数学形态学和边缘检测算子以及木材腐朽图像的特征,选择多尺度多结构的形态学算法,首先对图像进行交替顺序多尺度结构元素的膨胀、腐蚀滤波;再用多结构元素对图像进行开闭运算达到去除噪声,保留图像细节的目的;最后利用Canny算子提取图像的边缘特征。实验结果表明该方法抗噪能力强,能有效提取图像的边缘特征。

| Abstract: | According to the theory of mathematical morphology,edge detection operators and characteristics of rotten wood image,a multi-structure element with multi-scale edge detection algorithm based on mathematical morphology was proposed.In order to remove noise and preserve image details,the image was filtered by an alternative-order morphological corrosion-expansion filter with multi-scale element,and the edge information was obtained using multi-structure elements open-close operation.Canny operator was used to... |
