Register or Login to view.So, if there is (R,G,B) -> (Ink, Paint, Vellum) (or whatever it is detecting), which always produces the same result for the same R, G, B and the result doesn't change a lot visually if I replace all original RGBs with (R + r1, G + r2, B + r3) were r1, r2, r3 are reasonably small random integers, say [-2, 2], then I'd say the whole pipeline looks reasonable.
The report I just posted shows the results of that basic analysis. What do you think of them?
That test still does not try to detect the ink-under-paint "province", which is my ultimate goal. I have tried the latter already (with seven distinct color classes plus "OTHER") and the results are encouraging, although I have still not found the best subsets and the best way to combine the results (like ORing the "dark ink under green paint" map with the "faint ink under green paint" one, and things like that). Please stay tuned...
All the best, --stolfi
