This repository show the code to remove the background of the pictures using the U2Net pre-trained model.

The application has three simple functions:

1. Remove the background, producing a transparent PNG file.

2. Change the background by another picture.

3. Combine the image and multiple backgrounds to augment the dataset.

1. Clone this repository

git clone https://github.com/renatoviolin/bg-remove-augment.git
cd bg-remove-augment

2. Install dependencies

pip install -r requirements.txt

3. Download the pre-trained model

gdown --id 1ao1ovG1Qtx4b7EoskHXmi2E9rp5CHLcZ -O ./ckpt/u2net.pth

4. Start web-application

cd webapp
uvicorn app:app --host 0.0.0.0 --port 8000
