Presumable Bug: Even though Min, Max and Mean all give Zero the Median gives non-zero results.
I did not check this, but i could imagine that this could be connected to the fact that my intensity measurements are on a “masked” image and sometimes there are no foreground pixels within the objects.
so basically, it may be that the current implementation Median function cannot deal with 0 pixels…
may i have two connected question:
- how are masked images stored internally ?
- is it possible to convert a masked image into a “normal” image where all the background pixels are set to zero (such that it can be stored as a 8-bit tif) ?
