Studies on discrimination and segmentation method of touching milk somatic cell

The stack phenomenon existed in milk somatic cell pictures and the shape irregularity. In this paper, firstly a suitable shape factor selected judges whether it occurred in touching. This is in order to reduce false segmentation. An improvement watershed method is proposed which is mainly used in resolving the over-segmentation problem. The idea is obtaining the central points in the local maximum regions (seed points), and merging the redundancy seed points. Then the small areas are deleted after watershed segmentation. Finally segmentation points and segmentation lines are selected appropriately, too. Experiment shows the method can accurately and quickly separate touching milk somatic cell. The effect is obvious.
