Title:
PACKING PROJECTED OMNIDIRECTIONAL VIDEOS
Document Type and Number:
WIPO Patent Application WO/2018/045897
Kind Code:
A1
Abstract:
Aspects of the disclosure provide a method for packing a two-dimensional (2D) projected image of a spherical image in an omnidirectional video sequence to form a compact image. The method can include receiving a 2D projected image generated by projecting a spherical image of an omnidirectional video onto faces of a platonic solid. The 2D projected image has regions each corresponding to a face of the platonic solid. The method can further include rearranging the regions to form a compact image. At least two nonadjacent regions in the 2D projected image corresponding to two faces that are adjacent to each other along an edge on the platonic solid are arranged to be adjacent to each other along the same edge in the compact image. As a result, continuity between the two nonadjacent regions can be maintained.
