The most effective imagery takes into account the aesthetic, perceptual, and cognitive aspects of image creation. The goal of the emerging interdisciplinary field of Computational Aesthetics is to understand and formalize these aspects of image creation and to use this knowledge to improve the communicative quality of computer-generated imagery. This diverse collection brings together individuals with technical backgrounds who are developing computer-based tools to solve aesthetic problems, and people with artistic and design backgrounds who use these new tools in their work. Included papers provided a snapshot of the latest technical breakthroughs, and the most recent artistic or design achievements in applying computer-based techniques to solve aesthetic problems. The International Symposium on Computational Aesthetics in Graphics, Visualization, and Imaging (CAe’07) was held from June 20-22, 2007 at the Banff Centre for the Arts in Banff, Alberta, Canada.
