Molecular image‐processing devices based on chemical reaction systems. I: General principles for implementation

Abstract

Potentialities for implementing simple neural information-processing devices based on chemical and biochemical dynamical media are discussed. Pilot 'hardware' models of neural molecular devices that were able to perform image-processing operations were constructed.

“…This feature amounts to removing small details of a black-and-white image in its processing by an excitable medium. 5 If the input image is a dark ®gure on a bright background (Figs. 3 and 4), the accentuation of the least dark parts of the image proceeds.…”

“…In this case the process amounts to emphasising small features of a black-and-white image. 5 It should be noted that the character of the image evolution depends greatly on the state of the medium and could be changed by an appropriate choice of the medium state parameters (in our case, exposure to light excitation).…”
