Main window image processing to enhance visibility for the user (contrast/brightness)

[Stephen Gatesy]

Some simple image processing in the main windows would be useful to us. Maybe just min and max gray levels and gamma? There are times when we can't even find a point to choose for the detailed view.

This feature should probably be a little bit discussed and maybe we should divide it in 2. Just adding the same visual enhancement as in the detailview will be straightforward and it should be able to be done < 1 hour. E.g. we could have an extra button next to the zoom which opens a dialog where the settings can be performed.

If we want to do more filter, e.g. denoising, we have to discuss

• where and how to control them as we should be careful to not overload the UI? In this context it should be considered that the order of the filters plays a role
• which filters are useful?
• are they only visual enhancements for the user or also useful for tracking?
• how should they be implemented, e.g. XMALab would have to be able to use gpu-shader within a gpu pipeline which will require major implementations. (This might be less when autoscoper is integrated)

So for now i would suggest to only add the detailview filter to the mainwindows and to review more filter at a later stage, e.g. when incorporating autoscoper.

I think having the same enhancements as the detail view would be a great start, and likely sufficient for our lightest and darkest areas. Let's wait on denoising.

OK. I will prioritize this issue and add the enhancements for the main window with this. I will also open another ticket for the gpu processing and more filters so that we do not loose track of the ideas.

Opened new issue for gpu processing to also improve tracking : issue #11
