Abstract
There is provided a method and apparatus of encoding/decoding an image. The method comprises decoding information on block partitioning of a current block included in a current picture from a bitstream; determining a partitioning method of the current block on the basis of the information; and partitioning the current block by using the determined partitioning method, wherein the partitioning method is determined on the basis of whether or not the current block includes a predetermined boundary.
Claims12
A method of decoding an image, the method comprising:
- decoding information on block partitioning of a current block included in a current picture from a bitstream;
- determining a partitioning method of the current block on the basis of the information;
- and
- partitioning the current block by using the determined partitioning method,
- wherein the partitioning method is determined on the basis of whether or not the current block includes a predetermined boundary,
- wherein when the current block includes a lower boundary of the current picture, and a width of the current block is greater than a size of a largest transform block, the partitioning method is determined as partitioning other than horizontal binary-tree partitioning, and
- wherein the size of the largest transform block is 64.
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,
- wherein when the current block includes a lower boundary of the current picture, and a width of the current block is greater than a size of a largest transform block, the partitioning method is determined as partitioning other than horizontal binary-tree partitioning, and
- wherein the size of the largest transform block is 64.
A method of transmitting a bitstream, the method comprising:
- generating, with an entropy encoding unit, the bitstream by performing entropy encoding on information for decoding a current picture;
- and
- transmitting, with the entropy encoding unit, the bitstream including information on block partitioning,
- wherein the information on block partitioning is determined based on a partitioning method of a current block included in the current picture,
- wherein the current block is partitioned based on the partitioning method,
- wherein the partitioning method is determined based on whether or not the current block includes a predetermined boundary,
- wherein when the current block includes a lower boundary of the current picture, and a width of the current block is greater than a size of a largest transform block, the partitioning method is determined as partitioning other than horizontal binary-tree partitioning, and
- wherein the size of the largest transform block is 64.
