RGB To YUV
This algorithm converts RGB color model to YUV color space.
struct RGB
{
unsigned char R;
unsigned char G;
unsigned char B;
};
struct YUV
{
double Y;
double U;
double V;
};
struct YUV RGBToYUV(struct RGB rgb) {
struct YUV yuv;
yuv.Y = rgb.R * .299000 + rgb.G * .587000 + rgb.B * .114000;
yuv.U = rgb.R * -.168736 + rgb.G * -.331264 + rgb.B * .500000 + 128;
yuv.V = rgb.R * .500000 + rgb.G * -.418688 + rgb.B * -.081312 + 128;
return yuv;
}
Example
struct RGB data = { 82, 0, 87 };
struct YUV value = RGBToYUV(data);
Output
Y: 34.436
U: 157.663648
V: 161.925856
