This is basically the work being covered under the transparency branch
by Peter Ersts right now.

Well, provide tools for temporally modifying the image look up table,
like contrast stretch, so to adapt the grey/color scale in order to
see better/different. This is particularly useful when digitizing
satellite images. Example: an 8bit image has values 2 and 105 as min
and max respectively, with median around 35, a not unusual case of
satellite image that is awful to see. Solution: a tool that lets you
specify minimum and maximum values between which to interpolate
(linearly or not) to 0 - 255. That would make QGIS even better.

Just in case this website gives a good explanation of what enhancement means:
