Which is YUV?

Post by PengCon » Thu, 03 Dec 1998 04:00:00



Hi.
I read two paper about color image, found that there are 2 sets of YUV:
one is:
Y = 0.3 * Red + 0.6 * Green + 0.1 * Blue,
U = Red - Y;
V = Blue - Y;
the other is:
Y  =   0.299 * Red + 0.587 * Green + 0.114 * Blue
U  = -0.147 *  Red - 0.289 * Green +  0.436 * Blue
V  =   0.615 *  Red - 0.515 * Green -  0.100 * Blue
Which one is correct?
Thanks.

commonly said YCrCb

1. Feed JPEG with YUV (YUV -> YCbCr)

Hi,

I need to feed up the JPEG algorithm (Based on the JPEG Group sources) with
YUV (YUV422) format. Unfortunatelly, the original sources supports YCbCr
input which is NOT the same. Does anyone have an idea or solution for this
one?

Thanks,
Menachem
