1. A video decoding method comprising:
performing a first partitioning on a current image into a plurality of blocks; and
performing a second partitioning on a target block into a plurality of sub-blocks, wherein the target block includes a boundary of the current image among the plurality of blocks,
wherein the second partitioning is performed by recursively partitioning the target block,
wherein the second partitioning uses a quad-tree partitioning or a binary-tree partitioning, based on a predetermined condition relating to a size of the target block, wherein the predetermined condition is determined by comparing at least one of a size of a block capable of quad-tree partitioning and a size of a block capable of binary-tree partitioning with the size of the target block.
