The Segmentation of Overlapping Milk Somatic Cells Based on Improved Watershed Algorithm

In view of the shape irregularity and the stack phenomenon in milk somatic cell pictures. An improvement watershed method is proposed in the paper, which is mainly used in resolving the over-segmentation problem in watershed algorithm. Its main idea is: distance transformation is used for binary image firstly, obtaining the central points in the local maximum regions (seed points), and merging the redundancy seed points. This makes the over-segmentation problem was basically solved. Finally the small areas are deleted after watershed segmentation. Experiments show that the improved watershed method can accurately and quickly separate the milk somatic cells and control the over-segmentation. The effect is obvious.
