A missing color area extraction approach from high-resolution statue images for cultural heritage documentation

Abstract Ancient statues are usually fragile and have a tendency to deteriorate over time, developing cracks, corrosion, and losing color. Before any intervention on the object of art, a conservator must map degradation and take measurements. Deterioration mapping is an extremely long process, as th...
