Abstract
Disclosed are methods and apparatuses for decoding an image. A method includes receiving a bitstream obtained by encoding the image; dividing a first coding block into a plurality of second coding blocks; generating a prediction block of a second coding block based on syntax information obtained from the bitstream; and reconstructing the second coding block based on the prediction block and a residual block of the second coding block, the residual block being obtained by performing a dequantization and an inverse-transform on quantized transform coefficients from the bitstream. The first coding block has a recursive division structure. The first coding block is divided based on at least one of a quad tree division, a binary tree division or a triple tree division.
Claims8
A method for processing an image, the method comprising:
- obtaining block partitioning information from a bitstream;
- determining whether to divide a block into four partitions based on the block partitioning information;
- and
- dividing the block into the four partitions based on the block partitioning information.
A method for processing an image, the method comprising:
- determining whether to divide a block into four partitions;
- dividing the block into the four partitions;
- and
- encoding block partitioning information related to the dividing.
A method for transmitting a bitstream, the method comprising:
- determining whether to divide a block into four partitions;
- dividing the block into the four partitions;
- encoding block partitioning information related to the dividing;
- generating the bitstream including the block partitioning information;
- and
- transmitting the bitstream.
