| Abstract(in English) | This paper proposes a non-linear transformation model for integrating lateral inhibition and light/dark adaptation mechanisms. The transformation has the features; (a) it gives scale invariant graphical feature on the wide range of input stimuli, (b) it adjusts a non-linear S-potential response to quasi-linear response, and (c) it integrates a local and a global phenomena of physiological process in adaptation and feature extraction. This paper gives practical algorithms for gray image enhancement and scale invariant edge evaluation. Experimental results and discussions are also included in this report. |
