In a process for generating images using the mathematical framework of fractals implemented as a neural network architecture, processing for each pixel of the image is carried out by a respective processing element (10,11). All of the elements operate in parallel, thereby achieving very fast processing. The generated image is determined by the strengths of the connections between the processing elements. The processing elements may be individual elements or may be implemented in a computer. The image to be generated is preferably encoded as an Iterated Function System.
