SYSTEM AND METHOD OF STREAMING COMPRESSED MULTIVIEW VIDEO
Systems and methods are directed to streaming multiview video from a sender system to a receiver system. A sender system may capture an interlaced frame of a multiview video rendered on a multiview display of the sender client device. The interlaced frame may be formatted as spatially multiplexed views defined by a multiview configuration having a first number of views. The sender system may deinterlace the spatially multiplexed views of the interlaced frame into separate views. The sender system may concatenate the separated views to generate a tiled frame of a tiled video. The sender system may transmit the tiled video to a receiver client device, where the tiled video is compressed. The receiver system may decompress and interlace the views of the tiled video into streamed interlaced frames and render the streamed interlaced frames on a multiview display of the receiver system.
Systems and methods are directed to generating a three-dimensional (3D) model of a first image set. The first image set (e.g., input image set) corresponds to different viewing angles of an object that is subject to 3D modeling. A volumetric density function is generated from the first image set. A second image set (e.g., a textured image set) is generated from the volumetric density function and from a predefined color function. The first image set is blended with the second image set to generate a third image set (e.g., an image set with temporary textures). To generate the 3D model, a 3D surface model is generated from the third image set. In addition, a texture map of the 3D surface model is generated from the first image set. A computing system is configured to render the 3D surface model and texture map for display.
