| 摘 要： | 根据数学形态学的思想和木材图像的特性，选取适当的结构元素，通过腐蚀、膨胀、开与闭运算的加权组合，构造出形态学双梯度算法，并将它应用于木材腐朽图像的边缘检测。通过与经典边缘检测算法对比，该方法提取的图像边缘更加的准确、完整和连续；显现出更好的抗噪声能力和边缘检测能力，实验结果验证了该方法的可行性与有效性。

| Abstract: | According to the theory of mathematical morphological and characteristics of wood image, proper structuring elementwere selected to obtain mathematical morphological double-gradient algorithm via corrosion, expansion, and weighted array of opening operation and closing operation, which were then applied to edge detection of rotten wood image. Comparing with fast algorithm for edge detection, the obtained edges were more actuary, complete and continuous. In addition, better noise resisting abilities and edge detection abilities were shown. |
