Abstract: A source video stream is processed to extract a desired object from the remainder of video stream to produce a segmented video of the object. Additional relevant information, such as the orientation of the source camera for each frame in the resulting segmented video of the object, is also determined and stored. During replay, the segmented video of the object, as well as the source camera orientation are obtained. Using the source camera orientation for each frame of the segmented video of the object, as well as target camera orientation for each frame of a target video stream, a transformation for the segmented video of the object may be produced. The segmented video of the object may be displayed over the target video stream, which may be a live video stream of a scene, using the transformation to spatially register the segmented video to the target video stream.

Abstract: Techniques are presented for constructing a digital representation of a physical environment. In some embodiments, a method includes obtaining image data indicative of the physical environment; receiving gesture input data from a user corresponding to at least one location in the physical environment, based on the obtained image data; detecting at least one discontinuity in the physical environment near the at least one location corresponding to the received gesture input data; and generating a digital surface corresponding to a surface in the physical environment, based on the received gesture input data and the at least one discontinuity.
