Abstract: Techniques are presented for constructing a digital representation of a physical environment. In some embodiments, a method includes obtaining image data indicative of the physical environment; receiving gesture input data from a user corresponding to at least one location in the physical environment, based on the obtained image data; detecting at least one discontinuity in the physical environment near the at least one location corresponding to the received gesture input data; and generating a digital surface corresponding to a surface in the physical environment, based on the received gesture input data and the at least one discontinuity.

Abstract: Methods, systems, computer-readable media, and apparatuses for hierarchical clustering for view management in augmented reality are presented. For example one disclosed method includes the steps of accessing point of interest (POI) metadata for a plurality of points of interest associated with a scene; generating a hierarchical cluster tree for at least a portion of the POIs; establishing a plurality of subdivisions associated with the scene; selecting a plurality of POIs from the hierarchical cluster tree for display based on an augmented reality (AR) viewpoint of the scene, the plurality of subdivisions, and a traversal of at least a portion of the hierarchical cluster tree; and displaying labels comprising POI metadata associated with the selected plurality of POIs, the displaying based on placements determined using image-based saliency.
