By asking some questions I did not suggest they should be answered now.
I just hoped to direct the thinking/discussion towards quite obvious conclusion:
- do not focus on unnecessary stuff (e.g. controlling details of of histogram)
- focus on what we know to start prototyping/implementing early
- start from easy to complex
Obviously, solving a problem for a single channel is easier than
solving it for multiple channels and dimensions.
