Abstract: A device determines the positioning of objects in a scene by implementing a robust and deterministic method. The device obtains object detection data (ODD) which identifies the objects and locations of reference points of the objects in views of the scene. The obtained ODD is processed to identify a first image object of a first view as a mirror reflection of a real object. A virtual view associated with a virtual camera position is created, including the ODD associated with the first image object of the first view. The ODD associated with the first image object is removed from the first view. Based on the ODD associated with at least said virtual view and a further view of the one or more views, a position of said first image object is computed.

Abstract: A system and method are provided for controlling the own-voice experience of a user who talks while an earpiece is mounted to occlude an ear of the user. A vibration sensor is engaged with the user's head to sense vibrations formed by the user speaking and conducted by the user's head to the vibration sensor. A signal generator operates a speaker element, which is integrated with the earpiece, to generate sound waves in the ear canal of the user, based on the output signal of the vibration sensor. The signal generator generates the sound waves to at least partially cancel other sound waves that are generated by at least part of said vibrations entering the ear canal from surrounding bone and/or tissue. The system and method counteracts the occlusion effect and are applicable in connection with in-ear headsets, earphones, in-ear headphones, in-ear monitors, circumaural headphones, hearing aids, earplugs and earmuffs.
