Title: SYSTEM AND METHOD FOR IMPROVING EFFICIENCY IN ENCODING/DECODING A CURVED VIEW VIDEO
Abstract:
System and method can decode a curved view video. A decoder can obtain a mapping that corresponds a set of image regions in a decoded image frame to at least a portion of a curved view, and determine a padding scheme for the decoded image frame based on the mapping. Then, the decoder can construct an extended image for the decoded image frame according to the padding scheme, wherein the extended image comprises one or more padding pixels, and use the extended image as a reference frame to obtain another decoded image frame.
