Assignee: ZTE CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A method of video or picture processing, comprising:
acquiring a panoramic image having a width W, a height H and a depth D represented in three-dimensional coordinates;
mapping the panoramic image to a rectangular two-dimensional image comprising multiple regions including a top left portion representing a down view rotated 180 degrees in a counter clockwise direction, a top middle portion representing a left view rotated 90 degrees clockwise, a top right portion representing an up view, a bottom left portion representing a front view, a bottom middle portion representing a right view and a bottom right portion representing a back view of the panoramic image,
wherein the down view, the left view, the up view, the front view, the right view, and the back view are views according to a coordinate system defined by x, y, and z axes,
wherein the down view and the up view represent views along the y axis where the down view has a lower y coordinate value than that of the up view,
wherein the left view and the right view represent views along the x axis where the left view has a lower x coordinate value than that of the right view, and
wherein the front view and the back view represent views along the z axis where the back view has a lower z coordinate value than that of the front view;

determining a neighboring information of the multiple regions;
generating a video bitstream from of the panoramic image that includes the neighboring information; and
transmitting or storing the video bitstream.
