Shape-Adapting Gated Experts: Dynamic Expert Routing for Colonoscopic Lesion Segmentation

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • The introduction of Shape-Adapting Gated Experts (SAGE) marks a significant advancement in computer-aided cancer detection, particularly for colonoscopic lesion segmentation. This innovative framework addresses the challenges posed by cellular heterogeneity in gigapixel Whole Slide Images (WSIs) by enabling dynamic expert routing, thus enhancing adaptability to input variability.
  • SAGE's dual-path design, which combines a backbone stream with a selectively activated expert path, is crucial for improving the accuracy and efficiency of cancer detection systems. This development is expected to reduce redundant computations and enhance the model's performance in identifying lesions, ultimately contributing to better patient outcomes.
  • The evolution of AI frameworks like SAGE reflects a broader trend in the field of medical imaging, where hybrid architectures combining CNNs and Transformers are increasingly utilized. This shift is also evident in other applications, such as monkeypox detection and 3D object detection, highlighting the growing importance of adaptable and efficient models in addressing diverse medical and technological challenges.
