A novel implementation of watershed transform using multi-degree immersion simulation.
A novel implementation of watershed transform using a multi-degree immersion simulation is presented in this paper. The method is based on the improvement of traditional watershed by simulating immersion, which is originally proposed by Vincent & Soille in 1991. By changing the simulation procedure to multi-degree, which means the flood step is different on each degree of intensity, the proposed implementation resists the over segmentation problem effectively. After conducting a comparison of both the computing time and memory cost between the proposed method and a topographical distance based implementation, we draw the conclusion that the presented implementation achieves more accurate result with lower cost.
