Virtual Environment Construction

We are examining techniques for the creation and management of virtual reality analogues for the real world. This includes the automatic acquisition of image-based VR images, as well as the automated selection of viewpoints and scenes of interest. The selection of a set of representative pictures is referred to as the ``vacation snapshot problem''. In addition, selecting views of interest depends of the estimation of statistical properties of the environment. As a result, efficient exploration strategies to permit these statistics to be computed are very important, leading to a strategy we refer to as alpha-backtracking.
