[0037] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] A method for clustering brain fibers based on spatial path similarity of the present invention comprises the following steps:
[0039] 1), import fiber data, track out the fiber path, and calculate the similarity of each fiber;
[0040] 2) Due to the diversity of fiber data, some tissues have relatively scattered fibers and a small number of fibers, and some tissues have relatively dense fibers and a large number of fibers. According to the size of fiber data, two different fiber clustering methods are used: DPC(NGK) fiber clustering method and DPC(GK) fiber clustering method.
[0041] 2.1) For simple fiber data, the amount of fiber data is small, and the DPC (NGK) fiber clustering method is used: according to the density peak point, the clustering algorithm is quickly searched, that is, the DPC algorithm, and the corresponding density...
