This is a PyTorch implementation of SIFA for 'Unsupervised Bidirectional Cross-Modality Adaptation via Deeply Synergistic Image and Feature Alignment for Medical Image Segmentation.'
If you find this code useful, please consider citing my UDA research: FPL-UDA: Filtered Pseudo Label-Based Unsupervised Cross-Modality Adaptation for Vestibular Schwannoma Segmentation. You can access the research paper here, and the code is also available here.
If you wish to utilize the provided UnpairedDataset, please prepare your dataset in the following format. Please note that each individual data unit should be stored in an NPZ file, where '[arr_0]' contains the image data, and '[arr_1]' contains the corresponding labels:
your/data_root/
source_domain/
s001.npz
['arr_0']:imgae_arr
['arr_1']:label_arr
s002.npz
...
target_domain/
t001.npz
['arr_0']:imgae_arr
['arr_1']:label_arr
t002.npz
...
