Sharpness functions for computational aesthetics and image sublimation

The goal of this paper is to establish a link between existing autofocus methodology and computational aesthetics. Many existing autofocus methods are based on a sharpness function, a real-valued estimate of the image's sharpness. The intensity-based sharpness function has already been applied in computational aesthetics before. In this paper we apply a wider range of sharpness functions for aesthetics measurement in photographic images. Additionally, we use the full twodimensional result of the sharpness function in a visualization technique we term "sublimation".
