Abstract. In this paper we investigate and compare four aesthetic measures within the context of evolutionary art. We evolve visual art with an unsupervised evolutionary art system using genetic programming and an aesthetic measure as the ﬁtness function. We perform multiple experiments with diﬀerent aesthetic measures and examine their inﬂuence on the evolved images. To this end we store the 5 ﬁttest individuals of each run and hand-pick the best 9 images after ﬁnishing the whole series. This way we create a portfolio of evolved art for each aesthetic measure for visual inspection. Additionally, we perform a cross-evaluation by calculating the aesthetic value of images evolved by measure i according to measure j. This way we investigate the ﬂexiblity of each aesthetic measure (i.e., whether the aesthetic measure appreciates diﬀerent types of images). The results show that aesthetic measures have a rather clear ”style” and that these styles can be very diﬀerent. Fur...
