how to divide the whole brain vessels into multiple segments? #3

Thank you for your work and reply, and I have the following two questions to discuss with you: (1)I have one person's cerebral vessel segmentation result, but the current network input is vessel segment, how do I divide the whole brain vessels into multiple segments? (2)As for the calculation of Geodesic matrix, I tried the method of "Geodesics in heat", but due to the large amount of calculation, the speed is still very slow. Is there a faster calculation method?

Thanks for your attention! Here are the answers to your questions: (1) In our paper we directly use the processed segments provided by the IntrA dataset, and the detailed procedure to get segments from reconstructed 3D models is shown in their GitHub repositories. I remember they're using one software named Amira, where segments can be divided manually. (2) I think directly computing the geodesic matrix on the whole cerebral vessels may require a lot of time, while calculation on segments that only contain thousands of points is quick. Besides, you can try other algorithms from modern 3D processing libraries.
