Improved Segmentation of Polyps and Visual Explainability Analysis

arXiv — cs.LGFriday, December 12, 2025 at 5:00:00 AM
  • A new study introduces PolypSeg-GradCAM, an explainable deep learning framework designed for improved segmentation of gastrointestinal polyps during colonoscopy. This model integrates a U-Net architecture with a pre-trained ResNet-34 backbone and Gradient-weighted Class Activation Mapping (Grad-CAM) to enhance transparency in polyp analysis, addressing the challenges of manual segmentation which is labor-intensive and subject to variability.
  • The development of PolypSeg-GradCAM is significant as it aims to reduce colorectal cancer (CRC) progression by facilitating early and accurate detection of polyps, which are critical precursors to CRC. By improving the interpretability of deep learning methods, this framework could enhance clinical adoption and ultimately improve patient outcomes in colorectal cancer screening.
  • This advancement in automated polyp segmentation reflects a broader trend in medical imaging where explainability and accuracy are increasingly prioritized. The integration of explainable AI in healthcare is crucial, as it addresses the need for transparency in machine learning models, which is essential for gaining trust among clinicians and patients alike. Furthermore, the ongoing development of various deep learning frameworks highlights the competitive landscape in AI-driven medical diagnostics.
