This provides a mechanism to darken or brighten the image to reveal details from
over-saturated or dark regions, while maintaining the contrast. For example, the
following images show that lowering the brightness enhances the relevant details of
the target object since the pixels reside in the upper range and effectively shifts the
background darker.
Default Brightness = 128 Brightness = 50
