I haven't used my method for more than a year now, and I only applied it to a handful of pages.
Images are first smoothed and then R,G,B values are converted to Hue,Chroma,Lightness. In this, I am not tryng to do any mapping of hues to compensate for features of the human eye.
It then uses the ranges of these three values to make decisions on parchment, paint and ink.
For detection of faint ink and ink on a background of paint there are some additional tricks.
I know that that is still not sufficient, and some light brown paint that is easily detected by the human eye cannot yet be separated out. I know what I eventually want to do there, but that is a low-priority thing.
Right now it is the writing I am after.
