python3 ./fid_stats/gen_fid_stats.py --dataset 'ixi'  --source-domain 't2' --target-domain 'pd' --gpu-id 0

Options. See ./configuration/config.py for details.

--fid [default=true]
--noise-type 'slight'/'severe' [default='normal'] 
--identity [default=true]
--diff-privacy [default=true]

--debug --save-img --single-img-infer

Implementations of Data Processing

Sereval modes are described in the new settings of FedMed.

To reveal the real-world sitation in hosptials, datastream is organized as follows.

Load NIPRS Dataset, Generate Error Map, and Calculate Base Score for Human Judgement

python3 generate_nirps_err_map.py

Human Judgement

python3 artificial_scoring_system.py

Metric Consistency

python3 metric_consistency.py
