Method and apparatus for encoding/decoding image by using boundary processing, and recording medium for storing bitstream

A method of encoding an image, the method comprising:

• determining a partitioning method of a current block included in a current picture;
• partitioning the current block by using the determined partitioning method;
• and
• encoding information on block partitioning of the partitioning method,
• wherein the partitioning method is determined on the basis of whether or not the current block includes a predetermined boundary, and
• wherein when the current block includes a right boundary and a bottom boundary of the current picture and a width of the current block is greater than a size of a smallest quadtree block, the partitioning method is determined as quad-tree partitioning.

A non-transitory computer-readable medium storing a bitstream generated by an encoding method, the method comprising:

• determining a partitioning method of a current block included in a current picture;
• partitioning the current block by using the determined partitioning method;
• and
• encoding information on block partitioning of the partitioning method,
• wherein the partitioning method is determined on the basis of whether or not the current block includes a predetermined boundary, and
• wherein when the current block includes a right boundary and a bottom boundary of the current picture and a width of the current block is greater than a size of a smallest quadtree block, the partitioning method is determined as quad-tree partitioning.
