yuv信号怎么转成rgb信号

R = Y + 1.14V
G = Y - 0.39U - 0.58V
B = Y + 2.03U

void YUV2RGB(unsigned char *Y unsigned char *U unsigned char *V unsigned char *RGB int Width int Height int Stride) {
 for (int YY = 0; YY < Height; YY++)
 {
  unsigned char *LinePD = RGB + YY * Stride;
  unsigned char *LinePY = Y + YY * Width;
  unsigned char *LinePU = U + YY * Width;
  unsigned char *LinePV = V + YY * Width;
  for (int XX = 0; XX < Width; XX++ LinePD += 3)
  {
   int YV = LinePY[XX] UV = LinePU[XX] VV = LinePV[XX];
   LinePD[0] = int(YV + 2.03 * UV);
   LinePD[1] = int(YV - 0.39 * UV - 0.58 * VV);
   LinePD[2] = int(YV + 1.14 * VV);
  }
 }
}

按如下的公式进行计算可得出结果了
