1. A decoding method, comprising:
receiving a bitstream;
parsing the bitstream to determine that a current image block is required to be partitioned;
in response to determining that the current image block is required to be partitioned, parsing the bitstream to determine a partition direction, wherein the partition direction is a vertical direction;
partitioning the current image block into four rectangular subblocks based on the partition direction being the vertical direction, wherein a size of the current image block is expressed as W×16, with W representing a width of the current image block and 16 is a height of the current image block, wherein W is not equal to 16, and wherein a size of each of the four rectangular subblocks is expressed as W/4×16; and
reconstructing the current image block based on the four rectangular subblocks.
