Abstract: Sand painting is a very new and popular performance art technique, and the researches on computer-aided sand painting are growing rapidly, but most of the current works seem to be biased. Various features, including color pattern, color theme, color wheel, Benford index, fractal dimension, global contrast factor, Shannon entropy, colorfulness, data field complexity and Tamura texture, are introduced into the framework of computational aesthetics, and several sand performers are involved into the numerical calculation and statistics of sand painting art style. Then the computational aesthetics analysis on sand images is achieved. The experimental results suggest that, the computer-aided aesthetic evaluations can reflect the differences and similarities among the different types of sand images, which well correspond to human aesthetic perception, and as one of the useful bridge between sand painting art and computer-aided sand animation, the quantitative supplement is proposed for the subjective evaluation of sand painting art style, and then a reference is also provided for automatic creation of computer-aided sand animation.
