Adverse Cleaner as a tab extension for AUTOMATIC1111's webui.
You need to manually install opencv-contrib-python
because the webui uses opencv-python, so the extension can't modify the opencv package while running.
First you open the stable-diffusion-webui folder in terminal.
cd /path/to/stable-diffusion-webui
Activate venv,
./venv/Scripts/activate
Install opencv-contrib-python
pip install opencv-contrib-python
