| 摘 要： | 根据形态学梯度算法的思想,选取平坦的菱形为结构元素,通过腐蚀、膨胀、开与闭运算的加权组合,构造出一种形态学优化算法,并将它应用于木材缺陷图像的边缘检测中,使提取的图像边缘更加准确、完整和连续.通过与经典边缘检测算法对比,该方法有更好的抗噪能力和边缘检测能力,实验结果也验证了该方法的可行性与有效性.

| Abstract: | Based on the theory of morphological gradient algorithm,with a flat diamond chosen as structuring element,through weighted combination of erosion,dilation,opening and closing operations,a morphological optimization algorithm is constructed and it will be used for edge detection of defected wood images.The edges of wood images are more accurate,integrated and continuous.In contrast to the classical edge detection algorithm,the method performs better in noise-suppression and edge detection.The experimental results verify the feasibility and validity. |
