摘要： Methods and devices for cutting a three-dimensional image are disclosed. According to one example of the methods, a region of interest may be selected from an original three-dimensional image. A mesh model of the region of interest may be constructed. Then, distance field information and a shape index characteristic value of each mesh point in the mesh model may be obtained. A set of initiation points and a set of termination points may be obtained by splitting the mesh model according to the distance field information. Afterward, a mixed cost value of each mesh point may be obtained according to the distance field information, the shape index characteristic value and an image value of each mesh point. In this way, a cutting path may be determined from the set of initiation points and the set of termination points according to the mixed cost value.
