摘要 在深入研究柔性形态学边缘检测算法的基础上,提出自适应柔性形态学边缘检测算法,该算法是柔性形态学和自适应技术的结合。通过多方向结构元素的使用,取得其梯度的最大值,从而达到边缘检测较好的效果。通过比较移动结构元素窗口的信噪比和整个图像的信噪比,来实现该算法中自适应的特点。实验结果表明,该算法在边缘检测和抑制噪声方面,要比传统边缘检测算法有较好的效果,同时有较好的鲁棒性。 Based on study of soft morphology edge detection,a novel algorithm called adaptive soft morphological edge detection(ASMED) algorithm is proposed,which is combination of morphological and adaptive technology.By using five directional structuring elements,ASMED has capability of getting max of these gradients.So,ASMED has better effect of edge detection.Comparing the SNR of image and SNR of moving structuring window,which can achieve the characteristics of adaptive algorithm.Experiments show that ASMED is better than the traditional edge detection in edge detection and noise suppression.
