“…Memory lightness for example averaged higher by slightly more than one Munsell step, while memory hues tend to move towards the typical or dominant hues commonly associated with the test objects. Furthermore, most of the tested object colors showed increased chroma when recalled from memory, an overall trend, which has been confirmed in various subsequent experiments . However, some of the test objects of naturally low saturation like sand, skin, and concrete, did not show this effect, which was also confirmed by the findings of Pérez‐Carpinell et al who examined the memory induced shifts in dominant wavelength and colorimetric purity of eight familiar objects with the help of Munsell color patches assessed under different illuminants (D65 and A) while considering two different observer groups with varying degree of expertise regarding the technical and artistic aspects of color.…”

“…Several subsequent studies investigating the influence of memory on the perception of object colors validated Hering's claim by showing that the expectation of the color of an object being impressed on the observer's long‐term memory undeniably affects its perceived color . Independent experiments performed by Duncker, Bruner et al, and Harper for example revealed that the memory color, which is associated with a certain familiar object, has a significantly measurable impact on the observers' color matching results when the object is presented in such a way that its actual color is not the color characteristically identified with it, that is, a yellow banana illuminated by a red light source leads to a more yellowish color matching result than its actual color of presentation would suggest.…”

With the concept of memory colors being considered to play a crucial role for many imaging and lighting applications, the questions how people assess the color appearance of familiar objects and what kind of fundamental characteristics can be derived from these assessments have extensively been studied in the past. However, all of the previous studies, the authors of this article are aware of, lack in realistic viewing and adaptation conditions. In the attempt of overcoming these deficiencies, a new experiment investigating the impact of long‐term memory on the color appearance ratings of 12 familiar test objects was performed. The pooled observer data were modeled in CIECAM02 color space using bivariate Gaussian functions whose centroids define the corresponding memory color centers for each test object. Comparisons with previous results obtained by Smet et al. revealed no significant differences in the reported memory color centers, but showed distinct deviations in the covariance matrices defining the shape of the fitted distribution functions. It is supposed that this new set of functions will lead to significantly different results when being used for the construction of an updated memory‐based color quality metric.

Abstract:The effect of cross-regional or cross-cultural differences on color appearance ratings and memory colors of familiar objects was investigated in seven different countries/regions -Belgium, Hungary, Brazil, Colombia, Taiwan, China and Iran. In each region the familiar objects were presented on a calibrated monitor in over 100 different colors to a test panel of observers that were asked to rate the similarity of the presented object color with respect to what they thought the object looks like in reality (memory color). For each object and region the mean observer ratings were modeled by a bivariate Gaussian function. A statistical analysis showed significant (p < 0.001) differences between the region average observers and the global average observer obtained by pooling the data from all regions. However, the effect size of geographical region or culture was found to be small. In fact, the differences between the region average observers and the global average observer were found to of the same magnitude or smaller than the typical within region inter-observer variability. Thus, although statistical differences in color appearance ratings and memory between regions were found, regional impact is not likely to be of practical importance.

“…On evolutionary grounds 6,9 , one can argue that these perceptual structures are not intended to accurately match the physical world but, instead, are fast, intentiondriven explorations of the meaningless physical world in preparation of "optically guided potential behavior" 7,8 , thus striving for utility and efficiency, not veridicality. The efficacy of such mind-to-world approach to perception increases by making use of prototypes or templates like memory colors 10 or canonical visual size 11 . In a similar vein, this approach justifies the existence of reference-free techniques as a viable way of evaluating image quality 12,13 .…”

In the past decades perceptual (or perceived) image quality has been one of the most important criteria for evaluating digitally processed image and video content. With the growing popularity of new media like stereoscopic displays there is a tendency to replace image quality with viewing experience as the ultimate criterion. Adopting such a high-level psychological criterion calls for a rethinking of the premises underlying human judgment. One premise is that perception is about accurately reconstructing the physical world in front of you ("inverse optics"). That is, human vision is striving for veridicality. The present study investigated one of its consequences, namely, that linear perspective will always yield the correct description of the perceived 3D geometry in 2D images. To this end, human observers adjusted the frontal view of a wireframe box on a television screen so as to look equally deep and wide (i.e. to look like a cube) or twice as deep as wide. In a number of stimulus configurations, the results showed huge deviations from veridicality suggesting that the inverse optics model fails. Instead, the results seem to be more in line with a model of "vision as optical interface".
