||In augmented reality displays, X-Ray visualization techniques make hidden objects visible through combining the physical view with an artificial rendering of the hidden information. An important step in X-Ray visualization is to decide which parts of the phys- ical scene should be kept and which should be replaced by over- lays. The combination should provide users with essential percep- tual cues to understand the relationship of depth between hidden information and the physical scene.
In this paper we present an approach that addresses this deci- sion in unknown environments by analyzing camera images of the physical scene and using the extracted information for occlusion management. Pixels are grouped into perceptually coherent image regions and a set of parameters is determined for each region. The parameters change the X-Ray visualization for either preserving ex- isting structures or generating synthetic structures. Finally, users can customize the overall opacity of foreground regions to adapt the visualization.
