U-Mamba: Enhancing Long-range Dependency for Biomedical Image Segmentation

Ma, Jun, Li, Feifei, Wang, Bo

Understand

Convolutional Neural Networks (CNNs) and Transformers have been the most popular architectures for biomedical image segmentation, but both of them have limited ability to handle long-range dependencies because of inherent locality or computational complexity.

  • To address this challenge, we introduce U-Mamba, a general-purpose network for biomedical image segmentation.
  • Inspired by the State Space Sequence Models (SSMs), a new family of deep sequence models known for their strong capability in handling long sequences, we design a hybrid CNN-SSM block that integrates the local feature extraction power of convolutional layers with the abilities of SSMs for capturing the long-range dependency.
  • Moreover, U-Mamba enjoys a self-configuring mechanism, allowing it to automatically adapt to various datasets without manual intervention.
