Title:
APPARATUS OF INTER PREDICTION FOR SPHERICAL IMAGES AND CUBIC IMAGES
Document Type and Number:
WIPO Patent Application WO/2017/125030
Kind Code:
A1
Abstract:
Methods and apparatus of video encoding and decoding for a spherical image sequence and a cubic image sequence using circular Inter prediction are disclosed. For the spherical image sequence, the search window includes an area outside or crossing a vertical frame boundary of the reference frame for at least one block of the current spherical image to be encoded. Candidate reference blocks within the search window are determined, where if a given candidate reference block is outside or crossing one vertical frame boundary, the reference pixels are accessed circularly from the reference frame in a horizontal direction crossing the vertical frame boundary of the reference frame. For the cubic image sequence, circular edges of the cubic frame are determined. The search window includes an area outside or crossing a circular edge of the reference frame for at least one block of the current cubic frame to be encoded.
