Abstract: An electro-optical system that implements the self-tiling process of finding proper Iterated Function Systems for modeling natural objects. The system can operate in two different modes, a real-time interactive mode and an automated mode. The purpose of the system is to speed up the process of finding a proper IFS for a given object to be modeled. The system makes use of optical processing, including optical means for rotating, magnifying/demagnifying and translating an input image. Optical beamsplitters are used to combine transformed images to produce a tiled output image. In one embodiment, an automated controller evaluates the goodness of the match between the tiled image and the input image and generates control signals which cause adjustment of the settings of the optical means. The process is repeated automatically until the match is sufficiently good. The invention can also be operated in a manual, man-in-theloop mode.
