Swin-PSAxialNet: An Efficient Multi-Organ Segmentation Technique

Published on: July 5, 2024

  • A DSConv-ECA module is integrated before the ViT encoder for efficient local feature capture and reduced parameters.
  • The model was evaluated on five public datasets (Kvasir-SEG, CVC-ClinicDB, CVC-ColonDB, CVC-300, ETIS).

    • Main Results:

    • WCEDSAM achieved high performance with 15.38 million parameters.
    • Mean Dice (mDice) scores of 0.9383 on Kvasir-SEG and 0.9376 on CVC-ClinicDB.
    • Cross-domain mDice scores of 0.9189 (CVC-ColonDB), 0.8961 (CVC-300), and 0.7765 (ETIS), outperforming UNet++ and TransUNet.

    Conclusions:

    • WCEDSAM demonstrates superior performance in colorectal polyp segmentation compared to existing methods.
    • The model's lightweight design and novel feature extraction modules offer computational efficiency.
    • WCEDSAM shows significant potential for improving the accuracy and efficiency of colorectal cancer screening.
