Detailed Description

YUV to RGB 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;
