BlazeNeo: Blazing fast polyp segmentation and neoplasm detection

This repository provides code for paper "BlazeNeo: Blazing fast polyp segmentation and neoplasm detection" in IEEE Access, vol. 10, pp. 43669-43684, 2022.

Features

Real-time Speed: Our method, name BlazeNeo, can efficiently perform polyp segmentation and neoplasm detection from polyp videos with real-time speed (~81.5 FPS) on a single NVIDIA Tesla V100 GPU.
Cutting-edge Performance: Extensive experiments on the newly collected NeoPolyp dataset and comparisons to existing models. Moreover, we measure model latency and throughput on dedicated hardware in a setting similar to a real-life deployment.
