Landmark-Based Pedestrian Navigation with Enhanced Spatial Reasoning
Computer vision techniques can enhance landmark-based navigation by better utilizing online photo collections. We use spatial reasoning to compute camera poses, which are then regi...

Supporting interaction in augmented reality in the presence of uncertain spatial knowledge
A significant problem encounteredwhen building Augmented Reality (AR) systems is that all spatial knowledge about the world has uncertainty associated with it. This uncertainty m...
