| Abstract(in English) | The present study introduces a model for categorical color recognition, based on experimental data and the hierarchy of the human color vision system. The model has three stages which correspond to the photoreceptor, the opponent color mechanism and the categorical color mechanism levels. The simple network model with some AND-gates and two extractors of maximum response can precisely predict the categorical color recognition by operating on the opponent color responses regardless of the color appearance mode. In addition, we formulated age-related changes of vision and color vision deficiency, and introduce a real-time color vision simulator with parallel dynamic image processing which enables us to simulate elderly vision and dichromat vision. |
