Color Deconvolution / "Depainting"

[oshfdk]

You have not decoloured it why?

I'm not manually picking what to decolour, I only provide the model with a few samples of color and ink areas and the model tries to learn their properties and then apply them uniformly on the whole MS. Since I trained the model just on part of a few images mainly from the first part of MS, is doesn't work well on combinations of paints that it had no data on (e.g., it turned out to be not very good when depainting the water in balneological sections).

Looking specifically at the flower top, I'm not even sure it wasn't just painted (hatched) over with the same ink as the text. The hue is a tiny bit off, if you look at the hue channel in GIMP, but this looks more like text ink than anything else to me. If this is text ink, there is nothing I can do to depaint it using the models that process local pixel values.

Could you try it with your methods?

Most probably it won't work with visible light TIFFs, even if there is indeed some writing underneath. However, we are talking about f1v, which is the verso of f1r, for which we do have access to some MSI images. Unfortunately there are no TX (shine through) images for You are not allowed to view links. Register or Login to view. (as opposed to almost every other folio in the MSI set), but maybe something can be extracted from the existing images. I'll have a look.
