Right, a woman in front of a normal domestic scene, with hair extracted algorithmically, less accurately, and with higher computing requirements. Left, a man in front of a green screen, with well-extracted hair via Zoom's Virtual Background feature. However, the best mattes still require a green screen, as Zoom noted last Wednesday. This locus of academic and industry interest in AI extraction has already impacted the consumer space: crude but workable implementations are familiar to us all in the form of Zoom and Skype filters that can replace our living-room backgrounds with tropical islands, et al, in video conference calls. At Arxiv alone, papers related to innovations in machine learning-based foreground extraction are a weekly feature. The last ten years of GPU-accelerated computer vision research is ushering matte extraction into a third age, tasking researchers with the development of systems that can extract high-quality mattes without the need for green screens. Almost overnight, sixty years of the optical printing industry were consigned to history. It was now possible to remove the green (or whatever color) background just by searching for pixels within a tolerance range of that color, in pixel-editing software such as Photoshop, and a new generation of video-compositing suites that could automatically key out the colored backgrounds. In the 1990s, the digital revolution dispensed with the chemicals, but not the need for green screens. Here, Angela Lansbury is suspended on wires during the production of a VFX-laced sequence for ‘Bedknobs and Broomsticks' (1971). Disney's proprietary sodium vapor extraction process required backgrounds near the yellow end of the spectrum.
