Abstract
There is disclosed methods and apparatuses for multi-view video encoding, decoding and display. A depth map is provided for each of the available views. The depth maps of the available views are used to synthesize a target view for rendering an image from the perspective of the target view based on images of the available views.
Claims23
A method comprising:
- receiving at least one reference image having a corresponding depth image;
- synthesizing a set of pixels, each associated with a warped depth value, based on the at least one reference image and the corresponding depth image;
- segmenting the warped depth values of the set of pixels into a plurality of depth ranges;
- and
- transforming the at least one reference image into a synthesized image based on at least one depth range.
