X-Net: Hybrid Transformer–CNN Framework with Multi-Aspect Attention for Precise Colon Polyp Segmentation

Accurate localization of colon polyps plays a crucial role in the early diagnosis of colon cancer. In this paper, we propose a novel network architecture, X-Net, which integrates the Pyramid Vision Transformer (PVT) and EfficientNet-B0. We selected EfficientNet-B0 due to its optimized design and computational efficienc...
