Abstract:
Computerized analysis of paintings has recently gained interest. The
rapid technological advancements and the expanding interdisciplinary
collaboration present us a promising prospect of computer-assisted
authentication. We focus on the characterization of curve elegance.
Specifically, we propose measures of curve steadiness and
neighborhood coherence from brushstrokes. The technique has been
applied to the paintings of renowned aboriginal Canadian artist Norval
Morrisseau. Through computerized analysis of his authentic works and
the imitations, it is revealed that the curves in his authentic
paintings exhibit his commanding painting skills. The smooth and
steady flow of the curves show less hesitancy of the artist than the
authors of counterfeit works. The tangent angles tend to be more
consistent along curves in the authentic paintings than in the
imitations.
