BMSNet improves polyp segmentation in colonoscopy images using a novel boundary-guided multi-scale network. This method enhances computer-aided diagnosis for early colorectal cancer screening by accurately identifying polyps.

Area of Science:

  • Medical Imaging
  • Computer Vision
  • Artificial Intelligence

Background:

  • Accurate polyp segmentation is crucial for computer-aided diagnosis and early colorectal cancer screening.
  • Challenges include variations in polyp size, shape, texture, blurred boundaries, and low contrast.

Purpose of the Study:

  • To propose BMSNet, a boundary-guided multi-scale network for accurate polyp segmentation.
  • To address the limitations of existing methods in handling polyp variations and boundary ambiguity.

Main Methods:

  • Utilized an SMT-T backbone for efficient multi-level feature extraction.
  • Introduced a Boundary Prediction Module with bidirectional feature interaction and differentiable Canny-based supervision.
  • Designed a Boundary-Guided Feature Enhancement Module incorporating frequency-domain enhancement, multi-scale feature interaction, and boundary-guided modulation.
