Embodiment
[0082] The method of the present invention will be further described below through a specific example. This embodiment uses Matlab software to implement the algorithm described in the present invention, and is all completed on a computer that is equipped with a Core 2 Duo 2.2GHz processor, 2Gb internal memory, and an operating system of Windows7.
[0083] This example is for registering the surface of a left hemisphere of the brain. Before registration, it is first necessary to read the data on the surface of the left hemisphere of the brain, the data includes corresponding grid surface information, and the grid surface information includes vertex positions, connection relationships, and the like. The surface to be registered and the target surface such as Figure 5 As shown, the upper image is the surface to be registered, and the lower image is the target surface.
[0084] Step S1: Perform topological correction on the surface of the left hemisphere of the brain to be regi...
