Fig. 8From: Unveiling the invisible: mathematical methods for restoring and interpreting illuminated manuscriptsThe over-paint is IR transparent (“IR transparent original pigments” section). We perform seamless cloning on the subdmain marked in gray on the mask. Bottom left: result without Neumann boundary conditions, the green from the fig leaf is diffused across the edges. Bottom right: cleaner result using Neumann boundary conditions. The Neumann boundary conditions (b.c.) are marked by red lines on the maskBack to article page
