In Augmented Reality (AR), ghosted views allow a viewer to ex-plore hidden structure within the real-world environment. A bodyof previous work has explored which features are suitable to sup-port the structural interplay between occluding and occluded ele-ments. However, the dynamics of AR environments pose seriouschallenges to the presentation of ghosted views. While a modelof the real world may help determine distinctive structural features,changes in appearance or illumination detriment the composition ofoccluding and occluded structure. In this paper, we present an ap-proach that considers the information value of the scene before andafter generating the ghosted view. Hereby, a contrast adjustment ofpreserved occluding features is calculated, which adaptively variestheir visual saliency within the ghosted view visualization. This al-lows us to not only preserve important features, but to also supporttheir prominence after revealing occluded structure, thus achieving a positive effect on the perception of ghosted views.
