摘要:

AbstractThis article presents an overview of linear color‐vision models and presents a review of a general vision theory that provides for the derivation of linear models from an initial set of basic assumptions. The general theory specifies that the input and output terms of linear color‐vision models are to be regarded as stimulus and sensory perturbations, respectively, rather than as absolute stimulus and sensory magnitudes. The general theory also specifies that the weighting coefficients of linear color‐vision models correspond to first‐order derivatives of some set of nonlinear functions that represent the state of the visual system. The general theory provides a unifying framework that connects linear color‐vision models with linear models for spatial and temporal aspects

摘要:

AbstractStudies on observer metamerism reported so far are classified into two series. One is studies based on the color‐matching functions of Stiles's 20 observers. The other is experimental studies by using the Davidson and Hemmendinger (D‐H) Color Rule and color‐normal actual observers. The large discrepancy of the degree of observer metamerism between the above two series of studies was analyzed by using the color‐matching functions of Stiles's 20 observers and the D–H Color Rule. The results confirmed that the discrepancy in the observer‐metamerism indices was caused by different computational procedures used for deriving

摘要:

AbstractA standard deviate observer (SDO) has been formulated that can predict the average color mismatches of metameric color pairs by 20 Stiles' observers. A nonlinear optimization technique, rather than a statistical analysis, has been employed to derive it. The colorimetric characteristics of the present SDO are compared with those of SDOs previously proposed.

摘要:

AbstractA physiologically plausible model of colour vision, based on the CIE 1931 standard colorimetric observer, is shown to provide a colour order system giving reasonably good predictions of the unique‐hue loci, of constant‐hue loci, and of constant‐saturation loci, as judged by comparison with the Munsell and NCS systems, for daylight illumination. When combined with a chromatic‐adaptation transform of the von Kries type, the model is also shown to give quite good predictions for real surface colours seen in tungstenlight (SA) illum

摘要:

AbstractA leading writer in the field of color raises objections to the intrusion of factual science into the subjective realm of the artist. The plea is for greater tolerance.
