If this is autofluorescence of some sort, it is often broad wavelength, so one simple way to remove it is to take an image with a different fluorescence channel than your true signal and subtract the background image (noise)  from the signal image.  Dave

Hello
I try to improve my images before doing an Auto Threshold for the rest of the quantifications.
I have a significant background noise related to the Fibrin gel in which the cells develop.
In the attached images, the arrows point to areas I would like to "erase" and the cells are circled in green.

Any help will be welcome.
