Abstract: A system and processes provide a solution to object identification in images using a game environment to confirm the presence (or absence) of suspected points of interest in the real-world. A game environment uses data gathered by real-world sensors to replicate a real-world location as a gaming environment. Unconfirmed suspected points of interest (locations and/or objects) may be placed into the game environment. Various types of game play may be used to have players interact with the game environment. The actions by players may confirm whether a suspected point of interest is actually present in the real-world. Confirmation data of the presence of points of interest may be forwarded to an external database which may update a map file based on the data provided by player interaction in the game.

Abstract: Techniques for determining a direction of arrival of an emergency are discussed. A plurality of audio sensors of a vehicle can receive audio data associated with the vehicle. An audio sensor pair can be selected from the plurality of audio sensors to generate audio data representing sound in an environment of the vehicle. An angular spectrum associated with the audio sensor pair can be determined based on the audio data. A feature associated with the audio data can be determined based on the angular spectrum and/or the audio data itself. A direction of arrival (DoA) value associated with the sound may be determined based on the feature using a machine learned model. An emergency sound (e.g., a siren) can be detected in the audio data and a direction associated with the emergency relative to the vehicle can be determined based on the feature and the DoA value.
