This work is the pytorch implementation of TSGCN, which has been published in IEEE Transactions on Medical Imaging (https://ieeexplore.ieee.org/abstract/document/9594785/) and CVPR 2021 (https://openaccess.thecvf.com/content/CVPR2021/html/Zhang_TSGCNet_Discriminative_Geometric_Feature_Learning_With_Two-Stream_Graph_Convolutional_Network_CVPR_2021_paper.html).

To train the TSGCN, please put the trainning data and testing data into data/train and data/test, respectively. Then, you can start to train a TSGCN model by following command.

python train.py
