Abstract
A mobile device includes at least one imaging sensor to capture imagery of an environment of the mobile device, a privacy filter module, a spatial feature detection module, an assembly module, and a network interface. The privacy filter module is to perform at least one image-based privacy filtering process using the captured imagery to generate filtered imagery. The spatial feature detection module is to determine a set of spatial features in the filtered imagery. The assembly module is to generate an area description file representative of the set of spatial features. The network interface is to transmit the area description file to a remote computing system. The assembly module may select only a subset of the set of spatial features for inclusion in the area description file.
