Object intensity measurements: Add background subtraction

[tischi]

I think we should really add this somewhere:

Mean_Ratio = ( meanA - BG ) / (meanB - BG) Sum_Ratio = ( sumA - nPixelsA * BG ) / (sumB - nPixelsB * BG)

Where should we add it? I think we decided not to add it here and just use already BG-corrected images, but maybe that sends the wrong message.

We could rename: Global Background Correction to Background Measurement and Correction and then this module would be a prerequisite for Object intensity measurements.

What do you think?

[manerotoni]

Yes I think it belongs to Background assessment and correction. Would it make sense to reiterate the principle in the exercise with an image that is not background corrected. The students should spot the problem?

To keep it simple I would then only do an image without background correction, because that's what you typically have.

I'll just try to this now to object intensity measurements (because I need to teach this on Tuesday). We can then refactor those modules at some other time.

Concept map looks like this now:

The module does become more complex, but I think that's life...
