Various embodiments describe systems and processes for capturing and generating multi-view interactive digital media representations (MIDMRs). In one aspect, a method for automatically generating a MIDMR comprises obtaining a first MIDMR and a second MIDMR. The first MIDMR includes a convex or concave motion capture using a recording device and is a general object MIDMR. The second MIDMR is a specific feature MIDMR. The first and second MIDMRs may be obtained using different capture motions. A third MIDMR is generated from the first and second MIDMRs, and is a combined embedded MIDMR. The combined embedded MIDMR may comprise the second MIDMR being embedded in the first MIDMR, forming an embedded second MIDMR. The third MIDMR may include a general view in which the first MIDMR is displayed for interactive viewing by a user on a user device. The embedded second MIDMR may not be viewable in the general view.

Methods, systems, devices and computer software/program code products enable efficiently finding stereo correspondence between a feature or set of features in a first image or signal, and a search domain in a second image or signal.

An apparatus comprises a store (209) storing a set of anchor poses for a scene, as well as typically 3D image data for the scene. A receiver (201) receives viewer poses for a viewer and a render pose processor (203) determines a render pose in the scene for a current viewer pose of the viewer pose where the render pose is determined relative to a reference anchor pose. A retriever (207) retrieves 3D image data for the reference anchor pose and a synthesizer (205) synthesizes images for the render pose in response to the 3D image data. A selector selects the reference anchor pose from the set of anchor poses and is arranged to switch the reference anchor pose from a first anchor pose of the set of anchor poses to a second anchor pose of the set of anchor poses in response to the viewer poses.

There is provided an information processing apparatus, information processing method, and recording medium that each allow a user to recognize a border of a virtual space without breaking the world view of the virtual space. The information processing apparatus includes a control unit that tracks a motion of a user to present an image of a virtual space to the user, and performs distance control to increase a distance between a viewpoint of the user and a border region in the virtual space while an operation of the user coming closer toward the border region is being inputted. The border region is fixed at a specific position in the virtual space.

Aspects of the subject disclosure may include, for example, transmitting viewpoint information associated with a first portion of a three-dimensional (3D)/volumetric video to a device, wherein the viewpoint information comprises a first coordinate in 3D space associated with a first viewing direction in a playback of the first portion and a first timestamp associated with the first portion, receiving, from the device, a multiplane image (MPI) representation of a second portion of the 3D video responsive to the transmitting of the viewpoint information, and providing an image of the MPI representation to a display device. Other embodiments are disclosed.
