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.
