Abstract: The overlapping phenomenon often appears in the cell image recognition.It is necessary to design an effective algorithm to separate the clustering cells into single ones.Most of the existed separating algorithms are based on Mathematical Morphology，but all algorithms have limitation.An algorithm based on improved math morphology separating is presented in the paper for the problem.Using a simple and fast contour separating computation the algorithm can obtain transformed distance.Then，it uses the watershed method to separate cells.Experimental results show that the algorithm has a good separation effects.
