Take the tour ×  $$ \begin{pmatrix} Y \\ Cb \\ Cr \end{pmatrix}
= \mathrm{Round} \left\{ \begin{pmatrix}
0.2126\times\frac{219}{255} & 0.7152\times\frac{219}{255} &
0.0722\times\frac{219}{255} \\
-\frac{0.2126}{1.8556}\times\frac{224}{255} &
-\frac{0.7152}{1.8556}\times\frac{224}{255} &
0.5\times\frac{224}{255} \\ 0.5\times\frac{224}{255} &
-\frac{0.7152}{1.5748}\times\frac{224}{255} &
-\frac{0.0722}{1.5748}\times\frac{224}{255} \end{pmatrix}
\begin{pmatrix} R \\ G \\ B \end{pmatrix} \right\} +
\begin{pmatrix} 16 \\ 128 \\ 128 \end{pmatrix} $$  Is it
possible to derive formula from above matrix that converts YCbCr
to RGB? I am newbie to maths.  I have YCbCr value already
available, I want to convert it to RGB.  share|improve this
question You should be able to translate the formulae in the

interpreted his question as asking how to invert that
transformation in his linked equation; hence the wiki entry
containing the YCbCr▶RGB conversion, which can b
