| 摘 要： | 针对纤维图像的特点,提出了纤维掩码计算算法中的阈值计算方法,使得计算结果中纤维的轮廓信息具有高信噪比以及良好的连续性.此外,克服了Canny算子在纤维边缘检测中输出的伪边缘以及多重边缘的缺点,为后继纤维识别算法提供了更准确的轮廓信息.

| Abstract: | A threshold determination algorithm for fiber mask calculation was proposed,in which some shortcomings of Canny algorithm was overcame,such as fault edge output and multi-edge output in Canny operator inspection.With this algorithm,the fiber's profile information with high signal-noise-ratio and good continuity can be obtained,which provides correct information for fiber recognition. |
