Abstract: To segment the overlapping blood cells，an approach based on the characteristic that the blood cells are disk-shaped is proposed.A distance map and the edge of image can be obtained by morphological erosion，while the regional centers and centers of circle can be deserved with grayscale reconstruction algorithm.After all of these，the edge of the blood cells is searched based on the circular characteristics to find the separating points and separating line，then the overlapping blood cells are segmented into singles accurately.The experimental results show that the proposed approach is feasible and effective.

摘要： 提出一种基于血细胞近圆形特征的粘连血细胞分割方法。用形态学腐蚀得到距离图和图像的边缘，并利用灰度重建得到细胞的中心区域和圆心，在此基础上基于细胞圆形特征对细胞的边缘进行搜索，得到粘连细胞的分离点，从而求得分离线，完成对粘连血细胞的精确分割。实验表明，该分离方法是有效可行的。
