Metamerism in the visual system

چکیده
For the colour industry, metamerism is an unpopular word since it implies different mixes of the colours of the spectrum which can be seen to be the same only under certain conditions of light. However, can this assessment be extended to the visual system? Or could metamerism be the system’s mechanism to balance the stimuli it receives? The results obtained bring to mind an assertion made by MacAdam to the effect that the law of additivity when applied to luminance is not applied to measurements of brightness. If in this case additivity cannot be considered, we are undoubtedly up against a non-linearity for which the system has to compensate. In this paper we shall seek to answer these questions

Frequency of metamerism in natural scenes.
Estimates of the frequency of metameric surfaces, which appear the same to the eye under one illuminant but different under another, were obtained from 50 hyperspectral images of natural scenes. The degree of metamerism was specified with respect to a color-difference measure after allowing for full chromatic adaptation. The relative frequency of metameric pairs of surfaces, expressed as a prop...
متن کاملColour Aspects in Photo-quality Ink-jet Printing
The topic of photo-equality in hardcopy technologies has been widely discussed from the beginning of digital printing until today. Photographic quality prints can be made on desk-top printers with little compromises in permanence and performance. The paper compares the status of ink-jet prints in professional and desktop systems with commercial photography. The gamut of typical ink-jet dye and ...
متن کاملOn Spatial Metamerism in Computational Vision
This dissertation considers spatial metamerism in computational vision. Metamerism occurs when sensory input fail to completely determine the physical reality and a whole class of stimuli will produce the same measurements. The term metamerism is borrowed from colour science, where several distinct spectra may result in the same perceived ’colour’. In spatial vision metamerism arise as a result...
متن کاملReducing observer metamerism in wide-gamut multiprimary displays
Emerging electronic display technologies for cinema and television such as LED, OLED, laser and quantum dot are permitting greatly enhanced color gamuts via increasingly narrow-band primary emission spectra. A recent standard adopted for Ultra High Definition television, ITU-R Rec. 2020, promotes RGB primary chromaticities coincident with the spectral locus. As displays trend towards larger gam...
متن کاملTowards Higher Dimensionality in Cinema Color: Multispectral Video Systems
The current digital transition being experienced by the motion picture industry has afforded an effective increase in dimensionality in the domains of time and space, however, comparatively little effort has been put into expanding a rigorous treatment of color. All practical motion imaging systems continue to rely on the metamerism illusion wherein a particular integrated stimulation of the th...
