Overview

Randomized trial demonstrates improved computational efficiency in pavement crack segmentation, suggesting practical applications.

Key Points

  • This research aims to develop a lightweight CNN-Mamba hybrid architecture for efficient pavement crack segmentation.
  • Proposed a hybrid architecture replacing MobileViT modules with EfficientViM-inspired blocks.
  • Refined segmentation with DCNv2-based deformable convolution.
  • Conducted experiments on the GAPs384 and CamCrack789 datasets to evaluate performance.
  • Increased inference speed from 1.49 to 4.44 FPS on GAPs384 and from 1.32 to 3.92 FPS on CamCrack789.
  • Reduced peak memory consumption from 2827 MB to 355 MB on both datasets.
  • Maintained clDice scores of 0.760 to 0.758 on GAPs384 and from 0.921 to 0.922 on CamCrack789.
