| 摘 要： | 针对棉纤维截面图像的边缘检测，对Canny边缘检测算子提出改进。在边缘跟踪算法中，引入边缘长度L和边缘分叉间平均间隔（像素数）L两个概念，在边缘跟踪算法中进行边缘类型评估。改进后的Canny边缘检测算子与传统Canny边缘检测算子相比，在同等实验条件下，确保了相同棉纤维边缘检出率的同时，更好地抑制了噪声引起的伪边缘输出。

| Abstract: | Edge detection for fiber cross-sectional images is studied in this paper,and the algorithm for improving Canny edge operator is proposed.The edge length L and the average edge phase L are presented to eliminate the fault edge output.With the improved Canny edge operator,the fiber edge output can be improved,and the fault edge output caused by noise can be removed effectively. |
