Abstract: A video processing method includes receiving a bitstream, and decoding, by a video decoder, the bitstream to generate a decoded frame. The decoded frame is a projection-based frame that has a 360-degree image/video content represented by triangular projection faces packed in an octahedron projection layout. An omnidirectional image/video content of a viewing sphere is mapped onto the triangular projection faces via an octahedron projection of the viewing sphere. An equator of the viewing sphere is not mapped along any side of each of the triangular projection faces.

Abstract: Methods and apparatus of processing cube face images are disclosed. According to embodiments of the present invention, one or more discontinuous boundaries within each assembled cubic frame are determined and used for selective filtering, where the filtering process is skipped at said one or more discontinuous boundaries within each assembled cubic frame when the filtering process is enabled. Furthermore, the filtering process is applied to one or more continuous areas in each assembled cubic frame.

Abstract: A method for performing image processing control and an associated apparatus are provided, where method may include the steps of: performing image coding on image information of at least one frame to generate encoded data of the at least one frame, wherein in the encoded data, a specific frame of the at least one frame includes a plurality of tiles, and each tile of the plurality of tiles includes a plurality of superblocks; and generating a bitstream carrying the encoded data of the at least one frame, wherein at least a partition type and a transform size of each superblock within a specific tile of the plurality of tiles are derivable from information corresponding to the specific tile within the encoded data, having no need to derive the partition type and the transform size from information corresponding to another tile of the plurality of tiles within the encoded data.
