摘要：Segmentation of 3D data (some time 4D data) is a very challenging problem in applications exploiting Marine GIS data. To tackle this problem, this paper proposes a topological approach based on the Digital Morse theory which is a kind of Discrete Morse theory to high dimension Grid points. The essence of the approach concerns detecting critical points in the High dimension Data, which represent parts of the topology changing. Because less or more some prior information could be got, our approach is quite robust against noise. Experimental results demonstrate the validity of our method
