Prepare Data

Set all dataset information to the dataset.yaml as follows.

Example of the config file (dataset.yaml):

# VCOD Datasets
moca_mask_tr:
  {
    root: "YOUR-VCOD-DATASETS-ROOT/MoCA-Mask/MoCA_Video/TrainDataset_per_sq",
    image: { path: "*/Imgs", suffix: ".jpg" },
    mask: { path: "*/GT", suffix: ".png" },
  }
moca_mask_te:
  {
    root: "YOUR-VCOD-DATASETS-ROOT/MoCA-Mask/MoCA_Video/TestDataset_per_sq",
    image: { path: "*/Imgs", suffix: ".jpg" },
    mask: { path: "*/GT", suffix: ".png" },
  }
cad:

    image: { path: "original_data/*/frames", suffix: ".png" },
    mask: { path: "converted_mask/*/groundtruth", suffix: ".png" },
  }

# ICOD Datasets
cod10k_tr:
  {
    root: "YOUR-ICOD-DATASETS-ROOT/Train/COD10K-TR",

  }

  }

Install Requirements

• torch==2.1.2
• torchvision==0.16.2
• Others: pip install -r requirements.txt

Evaluation

# ICOD
python main_for_image.py --config configs/icod_train.py --model-name <MODEL_NAME> --evaluate --load-from <TRAINED_WEIGHT>
# VCOD
python main_for_video.py --config configs/vcod_finetune.py --model-name <MODEL_NAME> --evaluate --load-from <TRAINED_WEIGHT>

Note

Evaluating performance on the VCOD dataset directly using training scripts is not consistent with the paper. This is because the evaluation approach in the paper continues the strategy of previous work SLT-Net, which adjusts the range of valid frames in the sequence.

To get the results in our paper, you can use PySODEvalToolkit and use the similar command as:

python ./eval.py `
    --dataset-json vcod-datasets.json `
    --method-json vcod-methods.json `
    --include-datasets CAD `
    --include-methods videoPvtV2B5_ZoomNeXt `
    --data-type video `
    --valid-frame-start "0" `
    --valid-frame-end "0" `
    --metric-names "sm" "wfm" "mae" "fmeasure" "em" "dice" "iou"

python ./eval.py `
    --dataset-json vcod-datasets.json `
    --method-json vcod-methods.json `
    --include-datasets MOCA-MASK-TE `
    --include-methods videoPvtV2B5_ZoomNeXt `
    --data-type video `
    --valid-frame-start "0" `
    --valid-frame-end "-2" `
    --metric-names "sm" "wfm" "mae" "fmeasure" "em" "dice" "iou"
