Just one of the many papers available in this collection of papers by Harold Cohen, creator of Aaron, the painter.
AARON is a program designed to investigate the cognitive principles underlying visual representation. Under continuous development for fifteen years, it is now able autonomously to make "freehand" drawings of people in garden-like settings. This has required a complex interplay between two bodies of knowledge: object-specific knowledge of how people are constructed and how they move, together with morphological knowledge of plant growth: and procedural knowledge of representational strategy.
I write programs which are intended to throw some light upon what people do, in a cognitive sense, when they make images: not upon what their images look like. Art is a series of acts, not a series of objects. From which it follows that nobody ever made original art - with or without a computer - by mimicking the appearances of existing original art.
Excellent summary of the development of the Aaron program through 1994.
