Chromakey RTC is an OpenCV component example that synthesizes two screens with chroma key. It is used with OpenCVCamera and CameraViewer component.
Chromakey is an RT component that realizes a technique called chroma key synthesis that makes an image taken with a specific color as the background (for example, green) and make it transparent then synthesize it with another screen. In this execution, it uses two OpenCVCamera components to capture two image data. The output uses CameraViewer component.
