Processes of segmentation of neighboring cells. (a) Grayscale image of two adjacent cells which are closed to each other; (b) grayscale image, (c) binary image, and (d) the matching result obtained from morphological operation (dilation followed by erosion); (e) distance transform image; (f) markers of the cells and background in different gray level values; (g) result of applying watershed transformation using the markers; (h) corrected identification of the two cells (the boundaries are indicated by red lines and their centers are indicated by red arrows).
