Comments on “A multi-stage color model”
A critical review is offered for the article entitled 'A multi-stage color model' by De Valois and De Valois [(1993) Vision Research, 33, 1053-1065]. This letter discusses (i) related literature, (ii) substantive problems, and (iii) the topic of color/luminance confounding.
متن کاملOn “A three-stage color model”
In regard to colored lights, an opponent cell will indeed increase its firing to luminance increments (as well as to equiluminant color increments) but this does not at all imply confounding; rathe, r, in both cases, the cell will signal more color. Alternatively stated, when one increases the luminance (or radiance, or energy, etc.) of a colored light, any theory must predict that its chromati...
متن کاملA multi-stage color model revisited: implications for a gene therapy cure for red-green colorblindness.
In 1993, DeValois and DeValois proposed a 'multi-stage color model' to explain how the cortex is ultimately able to deconfound the responses of neurons receiving input from three cone types in order to produce separate red-green and blue-yellow systems, as well as segregate luminance percepts (black-white) from color. This model extended the biological implementation of Hurvich and Jameson's Op...
متن کاملGeneralized industrial color-difference space based on multi-stage color vision and line-element integration
A generalized color-difference space was introduced based on theories of multi-stage color vision, for example, the zone theory, and extended by integrating line elements. This space had the following features: chromatic adaptation, a linear transformation from CIE tristimulus values to cone fundamentals, a nonlinear compression stage, a second linear transformation to opponent signals, and lin...
متن کاملComments on Color-Suppressed Hadronic B Decays
Recent experimental results on the color-suppressed nonleptonic decays B̄0 → D(∗)0π0 provide evidence for a failure of the naive factorization model and for sizeable relative strong-interaction phases between class-1 and class-2 B̄ → D(∗)π decay amplitudes. The allowed regions for the corresponding ratios of (complex) isospin amplitudes and a2/a1 parameters are determined. The results are interpr...
