TL;DR: Dyno-Net is a dynamic feature extraction model for gastrointestinal polyp detection, integrating adaptive multi-scale fusion, dynamic convolution, and boundary refinement, achieving superior accuracy and robustness.

Abstract: Gastrointestinal polyps are precursors to colorectal cancer, underscoring the need for accurate early detection. We propose Dyno-Net, a dynamic feature extraction framework integrating multi-scale fusion (DynoFPN), adaptive convolution (DynoConv), and boundary refinement (RefineDet\_LSCSBD), achieving 23.5\% higher fusion efficiency, 17.8\% better detection of small/atypical polyps, and mean IoU improvement from 0.68 to 0.81. Experiments confirm superior accuracy and robustness over mainstream detectors, demonstrating Dyno-Net’s clinical utility.
