									class RGB
{
public:
	unsigned char R;
	unsigned char G;
	unsigned char B;

	RGB(unsigned char r, unsigned char g, unsigned char b)
	{
		R = r;
		G = g;
		B = b;
	}

	bool Equals(RGB rgb)
	{
		return (R == rgb.R) && (G == rgb.G) && (B == rgb.B);

	double V;

	YUV(double y, double u, double v)
	{
		Y = y;
		U = u;
		V = v;
	}

	bool Equals(YUV yuv)
	{

	}

static RGB YUVToRGB(YUV yuv) {
	unsigned char r = (unsigned char)(yuv.Y + 1.4075 * (yuv.V - 128));
	unsigned char g = (unsigned char)(yuv.Y - 0.3455 * (yuv.U - 128) - (0.7169 * (yuv.V - 128)));
	unsigned char b = (unsigned char)(yuv.Y + 1.7790 * (yuv.U - 128));

	return RGB(r, g, b);
}
								

Example

									YUV data = YUV(82, 140, 87);
RGB value = YUVToRGB(data);
								

Output

									R: 24
G: 107
B: 103
