void RGB2YCbCr(unsigned char ***argRGB, double ***argYCbCr,

//下面又是另外在網路上找到的?
有人可以跟我說那個是正確的嗎?
Y = (77/256)R´   (150/256)G´   (29/256)B´
Cb = -(44/256)R´ - (87/256)G´   (131/256)B´   128
Cr = (131/256)R´ - (110/256)G´ - (21/256)B´   128
R´ = Y   1.371(Cr - 128)
G´ = Y - 0.698(Cr - 128) - 0.336(Cb - 128)
B´ = Y   1.732(Cb - 128)
//下面又是另一種轉法
Y = 0.257R´   0.504G´   0.098B´   16
Cb = -0.148R´ - 0.291G´   0.439B´   128
Cr = 0.439R´ - 0.368G´ - 0.071B´   128
R´ = 1.164(Y - 16)   1.596(Cr - 128)
G´ = 1.164(Y - 16) - 0.813(Cr - 128) -
0.392(Cb - 128)
B´ = 1.164(Y - 16)   2.017(Cb - 128)
有勞各位解答了,謝謝!
