Comments:
Calculates "(2*Blue - (Red+Green)) < thresh" for each pixel This is the same as U - 2.3*V in YUV space

Methods:

BlueScreenC(int nthresh = 40): Constructor.
void SetThreshold(int value): Get colour threshold
Values should be between 0 and 512
int GetThreshold() const: Get threshold used
void Apply(ImageC<ByteT> & mask,const ImageC<ByteRGBValueC> & image) const: Produce a background/foreground mask from an RGB image
255 is assigned to foreground, 0 otherwise
ImageC<ByteT> Apply(const ImageC<ByteRGBValueC> & image) const: Produce a background/foreground mask from an RGB image
255 is assigned to foreground, 0 otherwise
void Apply(ImageC<ByteT> & mask,const ImageC<ByteYUV422ValueC> & image) const: Produce a background/foreground mask from YUV 422 image
255 is assigned to foreground, 0 otherwise
ImageC<ByteT> Apply(const ImageC<ByteYUV422ValueC> & image) const: Produce a background/foreground mask from YUV 422 image
255 is assigned to foreground, 0 otherwise
