Abstract
Described herein is technology for, among other things, multiview coding with geometry-based disparity prediction. The geometry-based disparity prediction involves determining corresponding block pairs in a number of reconstructed images for an image being coded. The reconstructed images and the image represent different views of a scene at a point in time. Each corresponding block pair is projected on the image. This enables determination of disparity vector candidates. For each coding block of the image, a predicted disparity vector is determined based on the disparity vector candidates. Then, the predicted disparity vector may be utilized to obtain the bits to be encoded. The geometry-based disparity prediction reduces the number of encoded bits.
