Class NPPNativeMethods.NPPi.YUVToBGR

YUV to BGR color conversion.

Here is how NPP converts YUV to gamma corrected RGB or BGR.

Npp32f nY = (Npp32f)Y;

Npp32f nU = (Npp32f)U - 128.0F;

Npp32f nV = (Npp32f)V - 128.0F;

Npp32f nR = nY + 1.140F * nV;

if (nR < 0.0F) nR = 0.0F;

if (nR > 255.0F) nR = 255.0F;

Npp32f nG = nY - 0.394F * nU - 0.581F * nV;

if (nG < 0.0F) nG = 0.0F;

if (nG > 255.0F) nG = 255.0F;

Npp32f nB = nY + 2.032F * nU;

if (nB < 0.0F) nB = 0.0F;

if (nB > 255.0F) nB = 255.0F;
