RGB to YUV Conversion

      Y  =      (0.257 * R) + (0.504 * G) + (0.098 * B) + 16
      Cr = V =  (0.439 * R) - (0.368 * G) - (0.071 * B) + 128
      Cb = U = -(0.148 * R) - (0.291 * G) + (0.439 * B) + 128

YUV to RGB Conversion

      B = 1.164(Y - 16)                  + 2.018(U - 128)
      G = 1.164(Y - 16) - 0.813(V - 128) - 0.391(U - 128)
      R = 1.164(Y - 16) + 1.596(V - 128)

Alternative:

      Y = 0.299R + 0.587G + 0.114B
      U'= (B-Y)*0.565
      V'= (R-Y)*0.713

with reciprocal versions:

      R = Y + 1.403V'
      G = Y - 0.344U' - 0.714V'
      B = Y + 1.770U'
