How should I apply mathematical correction of the gray levels consisting of subtracting the 2nd degree polynomial that best fits (least square method) the homogeneous (low variance) areas of the gray-level image

Respected ImageJ users, i read in the paper
Color (and 3D) for Scanning Electron Microscopy, doi:10.1017/12
S1551929518000482

how they had done

applying mathematical correction of the gray levels. This
type of image processing consists of
subtracting the 2nd degree polynomial
that best fits (least square method) the
homogeneous (low variance) areas of
the gray-level image. In the corrected
image, each color represents a different
mineral phase that can yield a quantitative
volume fraction.

How can I do this in ImageJ, I would like to do this work in black and
white Scanning Electron Microscope Images. Thanks, with regards,
