The Ghosting Technique Applied to Augmented Reality Visualization

Functional realism focuses on delivering to the user the best visual information from the target scene. The virtual scenes/objects do not need to behave or look like the real ones, but they need to help users in tasks execution. In this sense, this paper focuses on functional realism applied to Augmented Reality scenes. The technique presented here applies a visualization technique called Ghosting to generate an importance map from the real scene in order to blend in the virtual objects in a more adequate way. A careless augmentation can prejudice the user Augmented Reality based experience. The importance map is built from a saliency map, edge detection, super pixel representation and texture analysis. We present results in outdoor and indoor environments in order to prove the technique effectiveness.
