1. A video decoding method comprising:
identifying that a right boundary of a first coding unit is outside of a right boundary of an image;
based on a height of the first coding unit being greater than a maximum transform size and a width of the first coding unit being greater than the maximum transform size, determining that a vertical binary split of the first coding unit is allowed;
based on the determining that the vertical binary split of the first coding unit is allowed, determining second coding units by splitting the width of the first coding unit in half in a vertical direction and decoding the second coding units;
based on the height of the first coding unit being greater than the maximum transform size and the width of the first coding unit being equal to the maximum transform size, determining that the vertical binary split of the first coding unit is not allowed and a horizontal binary split of the first coding unit is allowed; and
based on the determining that the vertical binary split of the first coding unit being not allowed and the horizontal binary split of the first coding unit being allowed, determining third coding units by splitting the height of the first coding unit in half in a horizontal direction and decoding the third coding units.
