METHOD AND APPARATUS FOR MULTIVIEW VIDEO ENCODING BASED ON PREDICTION STRUCTURES FOR VIEWPOINT SWITCHING, AND METHOD AND APPARATUS FOR MULTIVIEW VIDEO DECODING BASED ON PREDICTION STRUCTURES FOR VIEWPOINT SWITCHING

摘要

A multiview video decoding method includes receiving a base view image stream of a base viewpoint and additional view image streams of at least two additional viewpoints, restoring base view images by performing motion compensation that references base view anchor pictures of an I-picture type, by using the base view image stream, restoring a view decoding refresh image configured for viewpoint switching for changing a first additional viewpoint, by performing disparity compensation that references at least one of the restored base view images, on a first additional view image stream, and restoring first additional view images of the first additional viewpoint by performing at least one of disparity compensation that references the restored base view images and motion compensation that references restored images of the first additional viewpoint excluding the view decoding refresh image that precedes the restored first additional view images, on the first additional view image stream.
