transform_adjust_gamma

Also known as Power Law Transform. Intensities in RGB mode are adjusted
based on the following equation:
$$
 I_{\mbox{out}} = 255 \times \mbox{gain} \times \left
 (\frac{I_{\mbox{in}}}{255}\right)^{\gamma}
 $$

Provides access to datasets, models and preprocessing
facilities for deep learning with images. Integrates seamlessly
with the 'torch' package and it's 'API' borrows heavily from
'PyTorch' vision package.

transform_adjust_gamma function

<dl><dt>img</dt>
<dd>A <code>magick-image</code>, <code>array</code> or <code>torch_tensor</code>.</dd>
<dt>gamma</dt>
<dd>(float): Non negative real number, same as $\gamma$ in the
equation. gamma larger than 1 make the shadows darker, while gamma smaller
than 1 make dark regions lighter.</dd>
<dt>gain</dt>
<dd>(float): The constant multiplier.</dd></dl>
