A virtual background segments the person each frame and composites them over a chosen backdrop. The hard parts are clean edges around hair and fingers and stability under motion and changing light, all within a tight real-time budget.

AI for Video: A Complete Guide to Intelligence in Video Products: From Models and Inference to Computer Vision, Speech, Search, and Generative Video
A virtual background is judged by its edges: hair, fingers and fast motion are where users notice glitches first. Volume 6 covers the virtual background in detail within computer vision: segmentation and compositing, model choice, model artifacts and deployment topologies from browser to native client. Written by Nikolay Sapunov, CEO at Fora Soft.
