Abstract
A target view to a 3D scene depicted by a multiview image is determined. The multiview image comprises multiple sampled views. Each sampled view comprises multiple texture images and multiple depth images in multiple image layers. The target view is used to select, from the multiple sampled views of the multiview image, sampled views. A texture image and a depth image for each sampled view in the selected sampled views are encoded into a multiview video signal to be transmitted to a downstream device.
Claims13
A method, comprising:
- decoding a multiview video signal into a set of two or more texture images and a set of two or more depth images for a set of two or more sampled views of a multiview image, each sampled view in the set of sampled views corresponding to a respective viewpoint in a set of viewpoints to a 3D scene;
- warping the set of texture images to a set of warped texture images of a target view based on the set of depth images, the target view representing a viewer's viewpoint that is not covered in the set of viewpoints;
- each texture image in the set of texture images and each corresponding depth image in the set of depth images corresponding to a respective viewpoint, to the 3D scene, in the set of viewpoints;
- each such texture image being warped to a respective warped texture image of the target view in the set of warped texture images of the target view based on each such corresponding depth image;
- blending the set of warped texture images of the target view into a blended warped texture image of the target view;
- causing a display image derived at least in part from the blended warped texture image of the target view to be rendered, to the viewer, on a display of a wearable device.
