Abstract: In order to blur a virtual object in a video in real time as the video is acquired by a device capturing a real scene, a salient idea is used which estimates an apparent motion vector between two successive images, being captured at two successive device poses, in which the apparent motion vector estimation is based on a motion of the device. The successive images are then filtered based on the estimated apparent motion vector.

Abstract: Aspects of the disclosure relate to vehicles capable of autonomous driving. These vehicles may include seats for accommodating different numbers of passengers. In some cases, the seats may be reconfigurable. For instance, a vehicle may include a first row of seating having a first, passenger use configuration. The first row may allow a passenger to sit in a seat of the first row of seating and access user input controls for the vehicle. The first row of seating may also have a second, folded configuration where the first row is in a folded configuration and no longer usable for passenger seating. The vehicle may also have a second row of seating. When the first row of seating is in the second, folded configuration, the second row of seating may still be usable for seating and may include additional legroom for the passenger as compared to when the first row of seating is in the first passenger use configuration.

Abstract: A method and device for rendering a scene including one or more real objects is described. A virtual object is associated with each real object, a virtual object associated with a real object corresponding to a virtual replica of this real object. The virtual replica is used to render a transformation that may be applied to the real object when for example hit by a virtual object, the virtual object then replacing the corresponding real object within the scene. To bring realism to the scene, texture information obtained from image(s) of the real object(s) is used to texture the visible part(s) of the transformed virtual object(s). The texture information is selected in the images by using information on the visibility of the parts of the real object(s) that correspond to the visible parts of the transformed virtual object(s).
