[0036] The technical scheme of the present invention will be further explained below in conjunction with the drawings.
[0037] The brain fiber clustering method based on spatial path similarity of the present invention includes the following steps:
[0038] 1) Import fiber data, track the fiber path, and calculate the similarity of each fiber;
[0039] 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 with a very large number of fibers. According to the size of the fiber data, two different fiber clustering methods are used: DPC (NGK) fiber clustering method and DPC (GK) fiber clustering method.
[0040] 2.1) For simple fiber data, the amount of fiber data is small, and the DPC (NGK) fiber clustering method is adopted: the clustering algorithm is quickly searched according to the density peak point, that is, the DPC algorithm, and the corresponding density threshold and radi...
