Measuring Stipple Aesthetics in Hand-Drawn and Computer-Generated Images
When people compare a computer-generated illustration to a hand-drawn illustration of the same object, they usually perceive differences. This seems to indicate that the two kinds of images follow different aesthetic principles. To explore and explain these differences, we compare texture stippling in hand-drawn and computer-generated illustrations, using image processing analysis techniques and stipple distribution statistics. The image below illustrates one of the results in which different parts of hand-drawn and computer-generated stipple illustrations are compared and their correlation, contrast, and energy is analyzed.
