Abstract: Methods and apparatus are described that enable augmented or virtual reality based on a light field. A geometric proxy of a mobile device such as a smart phone is used during the process of inserting a virtual object from the light field into the real world images being acquired. For example, a mobile device includes a processor and a camera coupled to the processor. The processor is configured to define a view-dependent geometric proxy, record images with the camera to produce recorded frames and, based on the view-dependent geometric proxy, render the recorded frames with an inserted light field virtual object.

Abstract: An embodiment method for computationally adjusting images from a multi-camera system includes receiving calibrated image sequences, with each of the calibrated image sequences corresponding to a camera in a camera array and having one or more image frames. A target camera model is computed for each camera in the camera array and according to target camera poses or target camera intrinsic matrices for the respective camera. The computing generates a transformation matrix for each of the one or more first cameras. The transformation matrix for each of the one or more first cameras is applied to the calibrated image sequence corresponding to the respective camera. The transformation matrix warps each image frame of the calibrated image sequence and generates target image sequences.

Abstract: Embodiments are provided for achieving multi-view video foreground-background segmentation with spatial-temporal graph cuts. A multi-view segmentation algorithm is used where a four-dimensional (4D) graph-cut is constructed by adding links across neighboring views over space and for consecutive frames over time. The segmentation uses both the color values of each input image and the image difference between the input image and the background image to obtain an initial graph-cut, before adding the temporal and spatial links. By using the background subtraction results as the initial segmentation seed, no user annotation is needed to perform multi-view segmentation.

Abstract: Methods and devices permit a user to insert multiple virtual objects into a real world video scene. Some inserted objects may be statically tied to the scene, while other objects are designated as moving with certain moving objects in the scene. Markers are not used to insert the virtual objects. Users of separate mobile devices can share their inserted virtual objects to create a multi-user, multi-object augmented reality (AR) experience.
