Abstract
A method of decoding a bitstream by an electronic device is provided. A block unit having a block size is determined from an image frame according to the bitstream. The number of one or more reference lines neighboring to the block unit is determined based on the block size. One of the one or more reference lines is selected based on the number of the one or more reference lines. The block unit is reconstructed based on the selected one of the one or more reference lines.
Claims20
A method of decoding a bitstream by an electronic device, the method comprising:
- determining a block size of a block unit from an image frame according to the bitstream;
- determining a number of one or more reference lines based on the block size;
- selecting one of the one or more reference lines based on the number of the one or more reference lines;
- and
- reconstructing the block unit based on the selected one of the one or more reference lines.
An electronic device for decoding a bitstream, the electronic device comprising:
- at least one processor;
- and
- a storage device coupled to the at least one processor and storing a plurality of instructions which, when executed by the at least one processor, causes the at least one processor to:
- determine a block size of a block unit from an image frame according to the bitstream;
- determine a number of one or more reference lines based on the block size;
- select one of the one or more reference lines based on the number of the one or more reference lines;
- and
- reconstruct the block unit based on the selected one of the one or more reference lines.
A method of decoding a bitstream by an electronic device, the method comprising:
- determining a block width and a block height of a block unit from an image frame according to the bitstream;
- determining a number of one or more reference lines based on the block width and the block height;
- set the one or more reference lines as a prediction line, when the number of the one or more reference lines is equal to one;
- select the prediction line from the one or more reference lines based on a line index, when the number of the one or more reference lines is greater than one;
- and
- reconstructing the block unit based on the prediction line.
