Real-time Webcam Background Replacement Web Application

Zoom-like feature: Real-time webcam background replacement with a Web UI + Cartoonification + Image filters implemented with FastAPI using WebSocket. (Also, utilizes JavaScript for frontend functionalities)

Demo:

Full demo on YouTube: https://youtu.be/00FC_3qZmZc
*I'm running on Mac M1 (no gpu+recording). So, it looks quite delayed especially when applying the CartoonGAN (Deep Learning model). But in general, the model/method is fast and efficient enough to run in realtime. You can try it yourself :)

Features:

  • Replace the webcam background with a selected prepopulated image or one uploaded by the user.
  • Two available models for background segmentation: Mediapipe (default) and Hugging Face (cannot be selected from the UI, but from code).
  • Cartoonify webcam stream with two options: OpenCV (Sequence of image processings) and CartoonGAN (Deep learning model).
  • Three available versions of CartoonGAN: int8, dr, and fp16 (again, cannot be selected from the UI, but from code).
  • Apply filters to the webcam stream. Available filters include Grayscale, Saturation, Brightness, Contrast.
  • Supports concurrent connections.

How to use:

  1. Clone this repository. (and make sure you have Docker installed)
  2. Build the Docker image using build.sh.
  3. Run the Docker container using run.sh.
  4. Access port localhost:8000 on a web browser.
  5. That's it.
