The linear models of brightness sensation.
An analysis and mathematical comparison of models underlying the phenomena of brightness and contrast are presented. The concept of self-excitation which has not so far been considered is introduced into the structure of the models. Mach Bands can be described by two essentially different but formally identical mechanisms. The phenomenon allows neither a functional explanation in terms of models presented heretofore nor an answer to the question whether data processing is based in the human visual system on integrating of differentiating of on both.
