Quality Assessment for CRT and LCD Color Reproduction Using a Blind Metric

Abstract

This paper deals with image quality assessment that is capturing the focus of several research teamsfrom academic and industrial parts. This field has an important role in various applications related to imagefrom acquisition to projection. Numbers of objective image quality metrics have been developed during thelast decade. These metrics are more or less correlated to end-user feedback and can be separated in threecategories: 1) Full Reference (FR) trying to evaluate the impairment in comparison to the reference image,2) Reduced Reference (RR) using some features extracted from an image to represent it and compare itwith the distorted one and 3) No Reference (NR) measures known distortions such as blockiness, blurriness,.. . without the use of a reference. Unfortunately, the quality assessment community have not achievedto a universal image quality model and only empirical models established on psychophysical experimentationare generally used. In this paper, we focus only on the third category to evaluate the quality of CRT(Cathode Ray Tube) and LCD (Liquid Crystal Display) color reproduction where a blind metric, based onmodeling a part of the human visual system behavior. The objective results are validated by single-mediaand cross-media subjective tests. This allows to study the ability of simulating displays on a reference one.
