Abstract: A method for estimating vehicle location by obtaining change events from an event camera's observations of a ground surface moving relative to the vehicle, determining a signature of the ground surface from the change events; and estimating the location using the signature. The change events may be processed to produce an 1st invariant representation of a ground surface patch for use as the signature. Alternatively, range measurements representing a patch may be used as the signature. A map is constructed having the representations of the ground surface patches including the locations of the patches. The same patch of ground surface is subsequently measured thereby obtaining a sequence of change events which are processed to produce a 2nd representation. The 2nd representation is matched to the map of 1st invariant representations. The location of the vehicle on the ground is determined based on the match.

Abstract: A system for performing instructions determined by received media-based messages, the system including an interface for receiving a media-based message from a system user; a database associating a plurality of specifications of media-based messages with respective stored instructions; a recognition engine for identifying a correspondence between a received media-based message and a stored specification of a media-based message. The system may include an instruction engine for performing an instruction associated with a stored specification of an media-based message for which a correspondence has been identified; an interface for receiving an activation request; and a database manager configured to process the activation request to generate publication data for creating a publication that may be recorded by a user to define a new media-based message and configured to adapt the database to include a specification of the new media-based message.
