The Voynich Ninja

I've been toying with ways to "depaint" the manuscript. The most recent work I can find is Landini's colour deconvolution from back in the early 2000s. I wanted to check if anyone knew of newer developments? Also, is there a significant set of "depainted" images anywhere? I can only find fragments of Landini's image results, and some cruder image work done by Pelling (focused on recovering painted-over text).

Thanks!
