| 摘要: |
| Canny算子应用于细胞图像分割，只要选择适当的参数就可以取得好的分割效果。在分析细胞图像直方图后，利用类间方差最大化阈值分割算法(Otsu)可以实现Canny算子中门限值的自适应选择。试验结果表明，Otsu算法应用于Canny 算子中的门限选择，改善了算法在细胞图像中的分割效果，提高了算法的自适应性能。 |

| Abstract: |
| Canny algorithm is used in the segmentation of the cell image and it can obtain better effect of segmentation by setting the appropriate parameters.After the histogram of cell image is analyzed,the Ostu algorithm can implement the two threshold's adaptive setting in Canny algorithm. From the test's result, it can be seen that the Otsu algorithm can solve the threshold's setting in Canny algorithm and it can improve the the effect of cell image's segmentation and the adaptive ability of Canny algorithm. |
