💡 Installation

Please check INSTALL.md for installation instructions.

🔥 Get Started

Step 1: Data Preparation

Option 1: Download data from official data link and convert to detection format.

  1. Download datasets from the following sources:

    Source Domain: CVC-ClinicDB Target Domain: Abnormal Symptoms ETIS-Larib KID

  2. Change the masks to coco style. Please refer to this link or write a script.

Option 2: Use our preprocessed data

  1. Download datasets and corresponding coco format annotations in the following links:

    Source Domain:

    CVC-ClinicDB: gDrive

    Target Domain:

    Abnormal Symptoms: gDrive ETIS-Larib: gDrive

Change the dataset dir

Change the dataset dir to your downloaded data path in here.

Step 2: Prepare the source-only model

Download the Source-only model from gDrive.

Step 3: Training SMPT/SMPT++

# Train the SMPT stage
python tools/train_net_mcd.py --config-file configs/sf/smpt_hcmus.yaml SOLVER.SFDA_STAGE 5

# Train the SSDF stage, need to modify "ann_file"(L348) in ./fcos_core/engine/trainer to the annotations of the training dataset.
python tools/train_net_mcd.py --config-file configs/sf/smpt_hcmus.yaml SOLVER.SFDA_STAGE 2

Step 4: Testing the trained model

# Test the trained model
python tools/train_net_mcd.py --config-file configs/sf/$YOUR YAML FILE$ SOLVER.SFDA_STAGE 5 SOLVER.TEST_ONLY True MODEL.WEIGHT $YOUR .pth WEIGHT$
