| 摘 要： | 本文描述了一种应用模糊集结合数学形态学对布氏硬度压痕图像进行压痕圆提取的新算法.该方法应用数学形态学理论对图像边缘进行了有效的提取边缘提取,针对灰值图像的特点,在选择结构元素时兼顾了结构元素的形状特征和灰度特征,从而保证了最佳的提取结果.在边缘提取之前为了提高压痕图像的质量,使图形的可用信息分离出来,还应用模糊集理论对...

| Abstract: | This paper described a new algorithm for round contour extraction of indent image on metal surface after Brinell hardness test.Morphological theory is employed to extract round contour of indent image effectively.Based on characteristic of grayscale image,structural element is chosen according to its shape feature and grayscale feature in order to acquire better result.Before the stage of contour extraction,fuzzy theory was employed to enhance indent image.Validity of this approach is demonstrated using sev... |
