[0031] To make the objectives, technical solutions, and advantages of the present invention will become apparent from the following drawings and with reference to specific embodiments, further supplement the present invention.
[0032] Refer Figure 1 ~ 3 A method of combining global and vascular segmentation neighborhood information, it is possible to optimize the extraction of feature information, reduces the loss of image information, comprising the steps of:
[0033] Data Preprocessing Step 1
[0034] Intracranial cerebral vascular system generally a relatively small volume percentage (about 1% to 5%), largely depends on the performance of the FMM background region (i.e., non-blood vessel region) fit, and the vascular region It fits dependent small. While the data retained in the context of large computing load can also cause, affect the processing time model; Therefore, the bias field correction and the skull removed, generating a training sample;
