Usage

  1. Clone this repo
git clone https://github.com/NathanUA/U-2-Net.git
  1. Download the pre-trained model u2net.pth (173.6 MB) or u2netp.pth (4.7 MB) and put it into the dirctory './saved_models/u2net/' and './saved_models/u2netp/'

  2. Cd to the directory 'U-2-Net', run the train or inference process by command: python u2net_train.py or python u2net_test.py respectively. The 'model_name' in both files can be changed to 'u2net' or 'u2netp' for using different models.

We also provide the predicted saliency maps (u2net results,u2netp results) for datasets SOD, ECSSD, DUT-OMRON, PASCAL-S, HKU-IS and DUTS-TE.
