segmentation and pixel size

[jeremyszym]

Describe the bug
-do not take into account pixel size : each optical config, it seems that the segmenter do not distinguish µm and px.
-area or vignette size take into account for the minimal esd ??

Quote from Fabien L :
Segmentation bug:
While assessing what was segmented, I figured out an inadequation in between what was requested as segmentation size and what was actually done: this gets really visible with the high magnification lens. Segmentation ignores the pixel size!!! With a segmentation limit at 5 (micron) I obtain objects with size at 5 pixels (with a pixel size of 0.53 µm) // 20 pixels of area => therefore here the error is of 2 time change in difference (if I ask to segment at 50µm I obtain 25µm etc)
