Background subtract

[PiMaV]

Not properly working when pre selecting an image. Result simply not as expected.

Take folder with 2 images.
Select "background subtract" and select an image from the same folder. By definion one image must be all 0. Yet its not the case

I cannot replicate this error. For me, this is working correctly, one image is 0 everywhere.
Did you uncheck the "Range" checkbox when normalizing? Only "background" should be checked.

I can confirm that when unchecking "Range" it works.
However, this is counter-intuitive; basically "Range", "Background" and "sliding- window" are different options that should be decoupled. HOWEVER, for some very weird applications, Range + Background could be a thing -> very low prio

• Either we separete the selctions completly (like radio buttons; you can only select one)
• Or we mark is as "additional".
• Something like :

Normalization

Generate Background image

use: mean/max/ etc.

• use sliding window or range
• add background
• intensity
• blur
• subtract or divide (in theory both is possible as well -> very low prio)

dont waste time on the low prio stuff
