OBS Background Removal:Go Live Without a Green Screen!

What is It?

obs-backgroundremoval is an open-source plugin for OBS Studio that uses real-time AI-powered background removal, allowing you to remove or replace your webcam background without using a physical green screen. Developed by royshil, this plugin enhances the streaming and recording experience with features like low-light enhancement and multi-platform compatibility.

Key Features

Background Removal & Replacement
- Automatically detects and masks human foregrounds to remove or replace backgrounds with images, videos, or transparency.
Virtual Green Screen Effects
- Offers Zoom/Teams-style background blur and virtual replacements—without requiring a physical backdrop.
Low-Light Enhancement
- Integrated enhancement models improve video quality in dark environments for better clarity.
Cross-Platform Support
- Compatible with Windows, macOS, and Linux (supports Flatpak, HOME install methods).
GPU Acceleration Options
- Utilizes DirectML on Windows, CoreML on macOS (M1/M2), and CUDA/TensorRT on Linux for efficient performance and reduced CPU usage.

Technical Principles

Foreground Segmentation: Models like SINet, PP-HumanSeg, and RobustVideoMatting generate high-quality masks to separate background elements.
Low-Light Enhancement: Integrates models such as TBEFN and URetinex-Net to automatically brighten and clarify dimly lit webcam feeds.
Hardware Acceleration: Supports diverse backends including DirectML, CoreML, and CUDA for optimal performance across platforms.
