Hi, All

我们开源了TorchSeg，其中包括我们复现的算法：DFN, BiSeNet, PSPNet.

TorchSeg

This project aims at providing a fast, modular reference implementation for semantic segmentation models using PyTorch.

Highlights

• Modular Design: easily construct a customized semantic segmentation models by combining different components.

• Distributed Training: >60% faster than the multi-thread parallel method(nn.DataParallel), we use the multi-processing parallel method.

• Multi-GPU training and inference: support different manners of inference.

• Provides pre-trained models and implement different semantic segmentation models.

Prerequisites

• PyTorch 1.0

• pip3 install torch torchvision

• Easydict

• pip3 install easydict

• Apex

• Ninja

• sudo apt-get install ninja-build

• tqdm

• pip3 install tqdm




Model Zoo

Supported Model


• FCN

• DFN

• BiSeNet

• PSPNet

Performance and Benchmarks

Non-real-time Methods

BiSeNet(ours)1: because we didn't pre-train the Xception39 model on ImageNet in PyTorch, we train this experiment from scratch. We will release the pre-trained Xception39 model in PyTorch and the corresponding experiment.

后续我们会开源更多复现的语义分割算法，欢迎大家 Star 和 Contribute~
