    - Converts an 8-bit UYVY image to RGB888. Using the equations of *The Image Processing Handbook* (Russ and Neal 2015) and dropping the primes for convenience gives:

\[ Y=K\_R R + K\_G G + K\_B B \]

\[ C\_b = 0.5 \left( \frac{B-Y}{1-K\_B} \right) \]

\[ C\_r = 0.5 \left( \frac{R-Y}{1-K\_R} \right) \]

and inverts to:

\[\begin{split} \begin{bmatrix}R\\G\\B\end{bmatrix} = \begin{bmatrix}1 & 0 & 2(1-K\_R)\\1 & -\frac{2( K\_R (1-K\_R)}{K\_G} & -\frac{2( K\_B (1-K\_B)}{K\_G}\\1 & 2(1-K\_B) & 0\end{bmatrix} \begin{bmatrix}Y\\C\_b\\C\_r\end{bmatrix} \end{split}\]

The color conversion parameters follow those from the ITU-R BT.601-7 recommendation of \(K\_R=0.299\), \(K\_B=0.114\), and \(K\_G=0.587\).

\[\begin{split} \begin{bmatrix}R\\G\\B\end{bmatrix} = \begin{bmatrix}1 & 0 & 1.402000\\1 & -0.344136 & -0.714136\\1 & 1.772000 & 0\end{bmatrix} \begin{bmatrix}Y\\C\_b\\C\_r\end{bmatrix} \end{split}\]

The OpenCV equivalent can be:

FadasImgProps_t srcProps = { w, h, 2*w };
    uint32_t dstStride = 3*w;
    
    FadasCvtYUV_UYVYtoYUV_R( uyvyimg, srcProps, yuvimg, dstStride );
    
    for( int r=0; r<h; ++r )
       for( int c = 0; c < w; ++c )
       {
           int idx = 3 * (w * r + c);
           uint8_t u = yuvimg[idx + 1];
           uint8_t v = yuvimg[idx + 2];
           yuvimg[idx + 1] = v;
           yuvimg[idx + 2] = u;
       }

    cv::Mat ocvRGBImage( h, w, CV_8UC3, const_cast<uint8_t*>(rgbimg) );

    - Scales 8-bit single-channel integer image intensities \((y)\) by subtracting a constant \((s)\), multiplying by another constant \((m)\), and then adding by another constant \((a)\).

\[ y' = m (y - s) + a \]

 Normalization typically occurs using patch-based or a globally measured mean \((s = \mu)\) and standard deviation \((m = 1/\sigma)\). 
\[ y' = (y - \mu)/\sigma \]

 Scaling to a new mean \((\mu')\) and width \((\sigma')\) can be combined into single constants \(m = \sigma'/\sigma\), \(s = \mu\), and \(a = \mu'\). 
\[\begin{split}\begin{eqnarray\*} y' &=& m (y - s) + a \\ &=& (\sigma'/\sigma)(y - \mu) + \mu' \end{eqnarray\*}\end{split}\]

 Because this routine outputs into 8-bit unsigned integers, values should be chosen accordingly. Incoming mean and standard deviation can be measured, however the targeted range and bias might be fixed to the requirements of the next algorithm in the processing pipeline. One possible example is \(\sigma'\approx 32\) and \(\mu'\approx 128\).

- Parameters:

    - - **src** – Pointer to the input image. **WARNING:** Must be 128-byte aligned.
- **srcProps** – Input image properties. **WARNING:** Stride (bytes) must be a multiple of 128.
- **normlz** – Input normalization parameters. **WARNING:**

    - normlz.sub \((s)\) has a limited valid range of \(-255 \le s \le 255\).

    - normlz.add \((a)\) has a limited valid range of \(-255 \le a \le 255\).
- **dst** – Pointer to the output image. **WARNING:**

    - Adequate memory must already be allocated to the image buffer.

- **dstStride** – Stride (bytes) for dst [dstStride &gt;= width].

    - Scales 8-bit three-channel color image intensities \((y\_i)\) by subtracting a constant \((s\_i)\), multiplying by another constant \((m\_i)\), and then adding by another constant \((a\_i)\).

\[ y'\_i = m\_i (y\_i - s\_i) + a\_i \]

 Normalization typically occurs using patch-based or a globally measured mean \((s\_i = \mu\_i)\) and standard deviation \((m\_i = 1/\sigma\_i)\) for each color channel.
