A series of psychophysical experiments using categorical judgment method was carried out to develop a colour
naturalness metric (CNM) for evaluating image quality of mobile displays. These experiments included colour
naturalness judgment and image-quality difference judgment. Through the former one, CNMs were trained and the latter
experiment tested the metrics. Two types of CNMs were newly proposed: nonlinearly decaying CNM and linearly
decaying CNM. In the CNMs, it was assumed that one familiar object in an image played a critical role to judge the
colour naturalness of the whole image. Through a performance comparison between objects' models, one critical object
in a scene was selected and with the critical object's model, the whole scene's colour naturalness was predicted.read more

Image quality evaluation for smart-phone displays at lighting levels of indoor and outdoor conditions
TL;DR: The experimental results show that the AMOLED displays perform better on colorfulness because of their wide color gamut, while the high pixel resolution and high peak luminance of the IPS panels help the perception of brightness, contrast, and sharpness.

Comprehensive model for predicting perceptual image quality of smart mobile devices.
TL;DR: The overall image quality could first be predicted by its two constituent attributes with multiple linear regression functions for different types of images, respectively, and then the mathematical expressions were built to link the constituent image quality attributes with the physical parameters of smart mobile devices and image appearance factors.

Image naturalness model based on prototypical memory colors (sky, grass, and skin)
Dalin Tian,Cheng Ji,Ming Lu +2 more
TL;DR: Zhang et al. as discussed by the authors generated an image database including three prototypical memory colors images (sky, grass, and skin) and their local processed images, and the distribution of naturalness followed by memory color positions was analyzed.

61.2: Image‐Quality Modelling of a Mobile Display under Various Ambient Illuminations
TL;DR: In this article, an adaptive image quality model that incorporates the ambient illumination conditions was developed by carrying out a series of psychophysical experiment for assessing the image quality under dark, bright and outdoor bright surround conditions.

Memory colors of familiar objects.
TL;DR: The memory colors of ten familiar, naturally occurring objects have been determined and each memory color tended to be more characteristic of the dominant chromatic attribute of the object in question; grass was more green, bricks more red, etc.

Chroma variations and perceived quality of color images of natural scenes
TL;DR: In this paper, a different constraint on color reproduc- ness itself was found to depend on both the experienced naturalness of chroma and its variability, namely, the experience of colorfulness.

The relationship between image fidelity and image quality
TL;DR: This work investigated the relationship between the perceived image fidelity and image quality of halftone textures by asking subjects to rank order a set of printed halftones on the basis of smoothness and reducing the contrast of each pattern until it was at threshold.

Memory and preference for the colors of objects
TL;DR: Results indicated that, for hue and brightness, memory and preference were quite accurate for the objects tested; however, all subjects remembered and also preferred all items to be more highly saturated, suggesting that access to memory for object color is independent of shape and texture information.
