A New Algorithm For Watershed Segmentation of Cells in Marrow

A new watershed segmentation algorithm of binary images based on the convex property of cells is proposed in this study. A distance map is developed to determine the number of seeds due to iterative erosion. The ultra-erosion aggregate is considered as seeds to separate the cell cluster, and images are grown by dilation from these seeds until all the image pixels are assimilated except the convex boundary. In order to speed up the computation while maintaining a good cell contour,the choice and growing of seeds are under control
