The cell overlapping and adhesion
phenomenon often exists in cell image processing. Separating overlapped cell
into single ones is of great important and difficult in cell image quantitative
analysis and automatic recognition. In this paper, an algorithm based on
concave region extraction and erosion limit has been proposed to judge and
separate overlapping cell images. Experimental results show that the proposed
algorithm has a good separation effects on analog cell images. Then the method
is applying in actual cervical cell image and obtains good separation result.
