This activity belongs to the GeoGebra book Voronoi Paintings. The procedure we are using is not valid for all paintings, whether figurative or abstract. In some cases, because the elements lack a sharp profile, as in Pollock's painting Number 1A. In others, because the silhouettes of the focal areas form a single group that dominates the entire painting, as in Goya's The Third of May in Madrid (Figure 16).

However, in other paintings, it is easy to isolate the different elements that capture our attention, as they are well-differentiated, as in Vincent van Gogh's The Bedroom in Arles (Figure 17).
