This repo is the official implementation of “Polyp-PVT: Polyp Segmentation with Pyramid Vision Transformers”.
1. Introduction
Polyp-PVT is initially described in arxiv.
Most polyp segmentation methods use CNNs as their backbone, leading to two key issues when exchanging information between the encoder and decoder: 1) taking into account the differences in contribution between different-level features; and 2) designing effective mechanism for fusing these features. Different from existing CNN-based methods, we adopt a transformer encoder, which learns more powerful and robust representations. In addition, considering the image acquisition influence and elusive properties of polyps, we introduce three novel modules, including
