Args:
result: output of an input_fn to an estimator, which should be one of:

(features, labels) with same constraints as below.
* A tuple (features, labels): Where `features` is a `Tensor` or a

def demosaic(cfa, pattern='RGGB'):

Returns the demosaiced *RGB* colourspace array from given *Bayer* CFA using
bilinear interpolation.
Parameters
----------
CFA : array_like
*Bayer* color filter array (CFA).
pattern : unicode, optional
**{'RGGB', 'BGGR', 'GRBG', 'GBRG'}**,
Arrangement of the colour filters on the pixel array.
Returns
-------
ndarray
*RGB* colourspace array.
Notes
-----
- The definition output is not clipped in range [0, 1] : this allows for
direct HDRI / radiance image generation on *Bayer* CFA data and post
demosaicing of the high dynamic range data as showcased in this
`Jupyter Notebook <https://github.com/colour-science/colour-hdri/\
