1. A method performed by at least one processor, the method comprising:
receiving a bitstream, that includes a picture, the picture partitioned into a plurality of coding tree units (CTUs), wherein at least one row or column of CTUs, among the plurality of CTUs of the picture, that is adjacent to a boundary of the picture has a size dimension that is smaller than a corresponding size dimension of each CTU among the plurality of CTUs that is not adjacent to any boundary of the picture; and
encoding the bitstream based on the plurality of CTUs,
wherein the at least one row or column of CTUs includes a first CTU row or a first CTU column of the picture that is adjacent to a top boundary or left boundary of the picture, respectively, and
wherein:
the at least one row or column of CTUs includes the first CTU column that is adjacent to the left boundary of the picture and a last CTU column that is adjacent to a right boundary of the picture, and the first CTU column and the last CTU column each have a width that is smaller than a width of each CTU among the plurality of CTUs that is not adjacent to any boundary of the picture, or
the at least one row or column of CTUs includes the first CTU row that is adjacent to the top boundary of the picture and a last CTU row that is adjacent to a bottom boundary of the picture, and the first CTU row and the last CTU row each have a height that is smaller than a height of each CTU among the plurality of CTUs that is not adjacent to any boundary of the picture.
