Abstract

Claims (21)

1 . A method for decoding an image, the method comprising:

receiving information on image partitioning for the image included in a bitstream;

obtaining a plurality of image partitions included in the image based on the information on image partitioning; and

decoding the plurality of image partitions,

wherein each image partition comprises a plurality of default encoding parts, each default encoding part is selected from a plurality of candidate default encoding parts, each candidate default encoding part is composed of one or more encoding sub-units, and

wherein the bitstream comprises information on rotation of the image.

2 . The method of claim 1 , wherein the plurality of candidate default encoding parts comprises first default encoding part identical to one encoding sub-unit and second default encoding part having consecutive two encoding sub-units.

3 . The method of claim 1 , wherein the information on image partitioning comprises information indicating image partitioning and partitioning type information indicating partitioning form.

4 . The method of claim 1 , wherein the information on image partitioning comprises information indicating scanning method for default encoding parts included in an image partition.

5 . The method of claim 4 , wherein the information indicating scanning method comprises a raster scan method and a clockwise scan method.

6 . A method for encoding an image, the method comprising:

obtaining a plurality of image partitions included in the image, information on image partitioning for the image being encoded into a bitstream; and

encoding the plurality of image partitions into the bitstream,

wherein each image partition comprises a plurality of default encoding parts, each default encoding part is selected from a plurality of candidate default encoding parts, each candidate default encoding part is composed of one or more encoding sub-units, and

wherein the bitstream comprises information on rotation of the image.

7 . A method for transmitting a bitstream, the method comprising:

obtaining a plurality of image partitions included in the image, information on image partitioning for the image being encoded into the bitstream;

encoding the plurality of image partitions into the bitstream; and

transmitting the bitstream,

wherein each image partition comprises a plurality of default encoding parts, each default encoding part is selected from a plurality of candidate default encoding parts, each candidate default encoding part is composed of one or more encoding sub-units, and

wherein the bitstream comprises information on rotation of the image.
