ANALYSIS OF COLOR-VISION MECHANISMS IN THE CHROMATIC-FREQUENCY DOMAIN

We have characterized the human colour-vision system from the standpoi nt of Information Theory, by the separate analyses of the responses of the different colour-vision mechanisms in terms of periodic energy sp ectral distributions. Within the domain of chromatic frequencies, we a nalyse how chromatic information is transmitted, according to the form alism of various current vision models, which enable us to appreciate more clearly the differences in the definitions which these models mak e for the different stages of chromatic perception. The results indica te that, to a greater or lesser degree, information is filtered for fr equencies above 6-7.2 cycles/400 nm.
