Chroma key is a technology used in motion picture, television and photographic applications to remove solid-colored backgrounds (usually green or blue) and replace them with transparency to enable background replacement. This technology is sometimes refefrred to color keying, colour-separation overlay, greenscreen or bluescreen.
In our implementation we use several two-layred elippsoids floating in the RGB, YUV or HLS colorspace cube to isolate color regions to be removed (made transparent) in the image.
We claim that our technology offers the best quality among PC-based solutions capable of performing in real-time.

Features
- Quality processing of image edges by a two-layred ellipsoid in a color space cube. Transparency between the two ellipsoids changes in a linear way from fully transparent to non-transparent. This is required for proper processing of objects like glass, glass reflections, shadows, sheets of water and other transparent and semi-transparent objects.
- Advanced anti-splil correction algorithm: for quality color processing on image edges.
- Several color ranges to process complex backgrounds.
- Support for RGB, YUV and HLS color spaces.
- Separate pin for mask output (to enable external keying).
- Separate pin for preview (video keyed over selectable background) to simplify tuning.
- Property page with ability to configure chroma key setting by interacting with a video frame from the source video.
