BackgroundRemover

A command line tool to remove background from video and image, brought to you by BackgroundRemover.app which is an app made by nadermx powered by this tool

Requirements

• python 3.6 (only one tested so far but may work for < 3.6)

• python3.6-dev

• torch and torchvision stable version (https://pytorch.org)

• ffmpeg 4.2+

How to install torch and fmpeg

Go to https://pytorch.org and scroll down to INSTALL PYTORCH section and follow the instructions.

For example:

PyTorch Build: Stable (1.7.1)
Your OS: Windows
Package: Pip
Language: Python
CUDA: None

To install ffmpeg

sudo apt install ffmpeg python3.6-dev

To install torch:

pip install --upgrade pip
pip install torch==1.7.1+cpu torchvision==0.8.2+cpu -f https://download.pytorch.org/whl/torch_stable.html

Installation

To Install backgroundremover, install it from pypi

pip install backgroundremover

Usage as a cli

Image

Remove the background from a local file image

backgroundremover -i "/path/to/image.jpeg" -o "output.png"

Advance usage for image background removal

Sometimes it is possible to achieve better results by turning on alpha matting. Example:

backgroundremover -i "/path/to/image.jpeg" a -ae 15 -o "output.png"

change the model for diferent background removal methods between u2netp, u2net, or u2net_human_seg

backgroundremover -i "/path/to/image.jpeg" -m "u2net_human_seg" -o "output.png"

Video

remove background from video and make transparent mov

backgroundremover -i "/path/to/video.mp4" -tv -o "output.mov"

###remove background from local video and overlay it over other video

backgroundremover -i "/path/to/video.mp4" -tov -tv "/path/to/videtobeoverlayed.mp4" -o "output.mov"

remove background from video and make transparent gif

backgroundremover -i "/path/to/video.mp4" -tg -o "output.gif"

Make matte key file (green screen overlay)

Make a matte file for premier

backgroundremover -i "/path/to/video.mp4" -mk -o "output.matte.mp4"

Advance usage for video

Change the framerate of the video (default is set to 30)

backgroundremover -i "/path/to/video.mp4" -fr 30 -tv -o "output.mov"

Change the gpu batch size of the video (default is set to 1)

backgroundremover -i "/path/to/video.mp4" -gp 4 -tv -o "output.mov"

Change the number of workers working on video (default is set to 1)

backgroundremover -i "/path/to/video.mp4" -wn 4 -tv -o "output.mov"

change the model for diferent background removal methods between u2netp, u2net, or u2net_human_seg

backgroundremover -i "/path/to/video.mp4" -m "u2net_human_seg"-tv -o "output.mov"

Todo

• convert logic from video to image to utilize more GPU on image removal
• remove duplicate imports from image and video of u2net models
• clean up documentation a bit more
• add ability to adjust and give feedback images or videos to datasets
• other

Reason for project

We made it our own package after merging together parts of others, adding in a few features of our own via posting parts as bounty questions on superuser, etc. As well as asked on hackernews earlier to open source the image part, so decided to add in video, and a bit more.
