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。
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.
