How to find the median filtered image after doing subtracting averaged image from original image

I have got an image obtained from microscope. I have done averaging and subtracted that image from original. Now I want to apply median filter and then use fibermetric command.

How can I do this?

filteredImage = medfilt2(differenceImage, [7, 7]);

Adapt as needed. I've never heard of or used the fibermetric() function.
