# Res2Net for object detection and instance segmentation
## Introduction
<!-- [ALGORITHM] -->
We propose a novel building block for CNNs, namely Res2Net, by constructing hierarchical residual-like connections within one single residual block. The Res2Net represents multi-scale features at a granular level and increases the range of receptive fields for each network layer.
