摘要
针对传统分水岭算法分割缺损胶囊图像会产生过分割的现象,提出了一种改进的分水岭算法:先对胶囊图像进行区域标记,再进行形态学滤波预处理平滑噪声,然后进行分水岭分割,最后进行区域合并,得到最终分割结果。通过多次试验和对残损胶囊的在线测试比较分析,证明这种改进的方法使过分割现象得到了很好抑制,能有效地分割胶囊图像,为后继胶囊图像的识别与分类提供了方便。
Segmentation defects capsule image will output over - segmentation phenomenon traditional watershed algorithm, this paper presents an improved watershed algorithm： first capsule image area marked morphological filtering pretreatment smooth noise, and watershed segmentation, and finally The region merging been the final segmentation results. The capsule image recognition successor by numerous experiments and comparative analysis of damaged capsules online test, this improvement makes the over - segmentation phenomenon inhibition experiments show that the segmentation method can effectively split capsule image, for provide a convenient and classification.
