Chroma Key Demo

Chroma Key Demo is an example demonstrating the Imaging SDK chroma key filter.

Tap on the upper original viewfinder to select a chroma key color (for example a green backdrop canvas) and use the color distance slider to adjust the threshold of the color range to be made transparent. Tap on the lower modified viewfinder to toggle between a video background and a "transparent" background.
