To generate labels, you can use FreeSurfer, which is an open-source software for normalizing brain MRI images. Here are some useful commands in FreeSurfer: Brain MRI preprocessing and subcortical segmentation using FreeSurfer. Reference: TransUnet ViT-pytorch VoxelMorph...
For VoxelMorph implementation, we implemented our approach using PyTorch on a computer equipped with an Nvidia RTX A2000 GPU and an Intel Xeon Silver 4208 CPU. The Adam optimizer with a learning rate of 10–4, and a default of 50,000 iterations. In our experiment, we split LPBA40 dataset...
The proposed method was implemented on Python 3.7 using Pytorch 1.13 as backend on GPU NVIDIA GeForce RTX 3060. We set the learning rate as 0.001, epochs as 1000, steps per epoch as 100, and batch size as 8. All the hyperparameters used during the training process are detailed in Table3...
