中文摘要：

针对现有细胞图像分割算法对噪声敏感,传统SLIC（simple linear iterative clustering）算法对边界分割不精确的问题,提出一种基于改进的SLIC融合区域合并的方法：首先对宫颈细胞图像进行均值漂移处理,消除细微噪声点;然后进行二维Otsu自适应阈值处理得到初始轮廓,应用SLIC算法得到超像素区域,并融合到原图中完成初始分割;最后,在初始分割图中进行初略标记获得交互信息,利用最大相似准则进行合并,不需要预先设定分割阈值,没有被标记的背景区域将成功合并到标记的背景区域,同时,没有被标记的目标区域会被识别出,有效地阻止与背景区域合并。对宫颈细胞图像进行大量的细胞质分割实验,结果表明本文算法能够在较短时间内准确识别出宫颈细胞的细胞质边缘。

英文摘要：

As the existing cell images segmentation algorithms are sensitive to noise and traditional SLIC（simple linear iterative clustering）algorithm can not divide boundary precisely,an improved SLIC method based on region merging is proposed to resolve the problems.First,the mean shift treatment is used to eliminate noise on the cervical cell images,then the two-dimensional otsu adaptive threshold processing is conducted to abtain the initial contour,then based on SLIC algorithm the superpixel region is obtained,and the superpixel regions are fused to the original image to complete the initial segmentation.Finally,in the initial segmentation map,the initial mark is used to obtain the mutual information,and the maximum similarity criterion is used to merge.In this way,no present threshold is needned.The non-marker background regions are merged with labeled automatically,while the nonmarker object regions are identified and avoided from being merged with background.Several experiments of dividing the cytoplasm are conducted for cervical cells images.The proposed algorithm can extract cytoplasm from a single-cell cervical smear image more accurately in a relatively short time.
