The standard RGB colour space (sRGB) has been proposed as a means for obtaining accurate reproduction of colour and tone for images displayed across the Internet, provided that they are viewed under the reference display and viewing conditions define

The present report concerns an experimental comparison between subjective and objective measures of standard colour test samples chosen to represent hard copy images. Three attributes of colour, hue, chroma and lightness were examined. The study inve

This paper explores the influence of the gamut of cathode-ray tube (CRT) display devices on the reproduction of real surface colours. The commonly shown two-dimensional colour gamuts of additive de...

This paper reviews the processes involved in the digitization, display and storage of medium-size collections of photographs, using mid-range commercially available equipment. Guidelines for evaluating the performance of these digitization processes

This paper follows and extends previously reported investigations into the ability of observers to match surface colour samples by synthesis using red, green and blue stimuli provided by a cathode ray tube (CRT) monitor, controlled by a computer and

An investigation is reported into visual comparisons between object colours and simulations on a cathode ray tube (CRT) monitor display. Experiments are described in which observers viewed a bipartite field in which two coloured areas were separated

The perceived quality of an image displayed on a computer monitor depends on a number of different factors that can affect viewers' preferences. Two of these are the luminance of the monitor display and the resolution of the image. The effect of lumi

Pixel-based images of food products are prepared and systematically perturbed in colour and lightness, and the changes quantified. Observations are reported in terms of CIELAB and pixel value, with...

The results of investigations into observer response to perturbations of colour prints with known CIELAB colour differences from a standard reproduction are assessed. The responses in terms of acceptability and perceptibility of colour differences ar

This paper examines the use of a colour reproduction index as a quality metric for the characterization of ten digital cameras in an attempt to achieve colorimetrically exact reproduction. This essentially extends the use of the index further into th
