A common feature of all these implicit or explicit attempts to simulate the
biological characteristics of information processing was that they were being
developed as numerical computational methods for information processing.
Attempts were also undertaken to build digital computing systems maximally
adapted to these computational approaches, in particular to perform cellular logical
operations. Nevertheless, they did not lead to significant results, apparently because
of the fundamental differences between the discrete digital methodology and
biological principles.

Image Processing: Reaction-Diffusion Media
and Mathematical Morphology
A reaction-diffusion medium is a physical information processing unit fundamen-
tally different from digital devices. Information is entered into the environment in
the form of natural fragments—images—and is processed by the medium without
