When Green Screen Meets Panoramic Videos: An Interesting Video Combination Framework

Abstract

In this paper, an interesting video combination framework was established based on Unreal Engine 4. By substituting the green screen image with panorama videos, our framework could produce lifelike synthetic videos in which the foreground is the portrait captured by real-time TV cameras whereas the background is a pseudo scenario generated by previously captured panorama videos. The pseudo background updates itself from the panorama video according to the pose information of the TV camera so that the portrait looks as if immersed into the pseudo scenario rather than the green screen.
