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
- Advanced anti-splil correction algorithm: for quality processing of image borders.
- Two borders for keying area - fully transparent and non-transparent. The transparency between the two borders changes in a linear way.
- 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.
