Abstract: The present disclosure relates to methods, devices or systems for detecting markers spread in an environment to estimate the pose of a device running an augmented reality application. Detecting markers and playing the AR application are two competitor tasks for the device's processing resources. When the number of markers to detect requires a substantial part of the device's processing resources, it may penalize the application processing. The present disclosure proposes different embodiments to optimize the marker list to detect according to the required processing resources for both tasks.

Abstract: In a situation where a capturing device is capturing a first image of a scene comprising a display device displaying a second image, a salient idea is to send both the captured first image and the second image, being displayed by the display device to a processing device, for comparatively processing the first and the second image to determine a characteristic associated with the display device. Being able to process the first image (comprising a displayed second image) together with the original second image advantageously allows to determine various characteristics associated with the display device that altered the displayed second image within the first image, making it different from the initial second image. Characteristics associated with the display device are for example a specular reflection occurring on the display device in the scene and disturbing the capture of the scene.

Abstract: A method, apparatus and system for estimating reflectance parameters and a position of the light source(s) of specular reflections of a scene include RGB sequence analysis with measured geometry in order to estimate specular reflectance parameters of an observed 3D scene. Embodiments include pixel-based image registration from which profiles of 3D scene points image intensities over the sequence are estimated. A profile is attached to a 3D point and to the set of pixels that display its intensity in the registered sequence. Subsequently, distinction is made between variable profiles that reveal specular effects and constant profiles that show diffuse reflections only. Then, for each variable profile diffuse reflectance is estimated and subtracted from the intensity profile to deduce the specular profile and the specular parameters are estimated for each observed 3D point. Then, the location of at least one light source responsible for the specular effects is estimated.

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).

Color intensity of at least one pixel of the 3D scene can thus be modified using at least the occlusion attenuation coefficient.

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 an electronic device for object tracking in a sequence of light-field captures. A data acquisition unit acquires a sequence of light-field captures, wherein each light-field capture comprises a plurality of views. A feature determining unit determines features of an initial visual appearance model for an object of interest in a reference view of a first light-field capture. A feature matching unit matches the features in the reference view and in the further views of the first light-field capture. A feature discarding unit discards features that cannot be well matched in all views of the first light-field capture. An appearance model building unit builds an updated visual appearance model for the object of interest based on the remaining features. Finally, a movement tracking unit tracks the movement of the object of interest in the sequence of light-field captures using the visual appearance model.
