This paper describes the research work associated with the CIE TC8-02 Colour Difference Evaluation in Images, which aims to derive an industrial colour-difference evaluation method that is appropriate for complex colour images. The main aim of the TC is to recommend a colour-difference formula for complex image together with suitable perceptibility thresholds for industrial applications. With this in mind, a set of experimental results for assessing perceptibility thresholds were accumulated using printed images. The results from different data sets were found to be quite consistent. This set of images are currently being circulated and assessed at different imaging companies.
