Ezquerro Rodríguez, José Miguel ; Carreño Sánchez, Fernando ; Zoido Chamorro, Jesús Manuel | John Wiley & Sons, Inc. | 2003-02A systematic method of analyzing the colorimetric behavior of a set of observers is proposed. The differences between each observer and a standard one are analyzed with different procedures in two color-representation systems. It is apparent tha[...]texto impreso

Due to the variability in the sets of color-matching functions, different real observers have associated different color-representation systems. This fact darks the true interpretation of the experimental results obtained for different observers[...]texto impreso
We present a discussion about the influence of luminance on the geometry of color-difference thresholds. By assuming that color matchings are normally distributed in XYZ space, we have shown [Appl Opt 38:208–219 (1999)] that the probability dens[...]texto impreso
Ezquerro Rodríguez, José Miguel ; Carreño Sánchez, Fernando ; Zoido Chamorro, Jesús Manuel ; Bernabeu Martínez, Eusebio | John Wiley & Sons, Inc. | 2001-08In this research we compare the colorimetric behavior of several observers. For color centers recommended by CIE we have produced large sets of spectral distributions, which are metameric for the CIE 1931 standard observer. For each one of the c[...]texto impreso
Presented in this article is a method for the determination of the Weber fraction by analyzing data obtained from color-matching experiments. The method is based on a rigorous analysis of the probability density function derived from discriminat[...]texto impreso
Carreño Sánchez, Fernando ; Ezquerro Rodríguez, José Miguel ; Zoido Chamorro, Jesús Manuel | John Wiley & Sons, Inc. | 2006-12We present an analytical method to analyze, from a theoretical point of view, the influence of color-matching functions on the perception of luminance thresholds. We show that the thresholds depend on the spectral responsivities of each observer[...]texto impreso
Carreño Sánchez, Fernando ; Ezquerro Rodríguez, José Miguel ; Zoido Chamorro, Jesús Manuel | John Wiley & Sons, Inc. | 2009-06An analytical method to determine how color-matching functions influence the perception of chromaticity differences is proposed. We show that, as a consequence of the observer metamerism, a metameric color-match perceived by one observer may app[...]
