Multi Atlas Segmentation of 3D Brain MRI Based on Unsupervised Learning

Change the direction between volume data and atlas data while training:

 train([atlas,volume],[volume,flow])

Use different metrics. Use dice score to evaluate model.

Label fusion

Models: MAS-2 MAS-3 MAS-4 MAS-5 (vm-1, vm-2 double)

Spatial transform: linear/nearest

Use dice score to evaluate model.

Based on Voxelmorph and Unsupervised learning for registration
