Chroma Key wthout Color Restrictions based on Asynchronous Amplitude Modulation of Background Illumination on Retroreflective Screens
A simple technique to avoid color limitations in image capture systems based on chroma key video
composition using retroreflective screens and light-emitting diodes (LED) rings is proposed and demonstrated.
The combination of an asynchronous temporal modulation onto the background illumination and simple image
processing removes the usual restrictions on foreground colors in the scene. The technique removes technical
constraints in stage composition, allowing its design to be purely based on artistic grounds. Since it only requires
adding a very simple electronic circuit to widely used chroma keying hardware based on retroreflective screens,
the technique is easily applicable to TV and filming studios.Vidal Rodriguez, B.; Lafuente, JA. (2016).
