Surround – the New Background?

Abstract

Reproducing colour transparencies on hard copy is a common cross-media reproduction task, in which the original and reproduction have different viewing conditions. Colour appearance models CIECAM97s and CIECAM02 have not been successful at predicting the effect of the different viewing modes, partly as a result of ambiguities over the effects of surround and background.New values were derived for surround parameters c and Nc, which gave an improved prediction of the appearance of the transparency. Also evaluated was a function which weights the surround and background luminances by the distance from the stimulus in determining the background luminance factor Yb. Although this technique yielded a small improvement in the prediction of the transparency appearance, it was not significantly better than the grey world assumption which sets Yb to 20%.
