Importance Masks for Revealing Occluded Objects in Augmented Reality

When simulating ”X-ray vision” in Augmented Reality, a critical
aspect is ensuring correct perception of the occluded objects position.
Na¨ıve overlay rendering of occluded objects on top of realworld
occluders can lead to a misunderstanding of the visual scene
and a poor perception of the depth. We present a simple technique
to enhance the perception of the spatial arrangements in the scene.
An importance mask associated with occluders informs the rendering
what information can be overlaid and what should be preserved.
This technique is independent of scene properties such as illumination
and surface properties, which may be unknown. The proposed
solution is computed efficiently in a single-pass fragment shaders
on the GPU.
