Abstract
A method of decoding a bitstream by an electronic device is provided. A block unit having a block height and a block width is determined from an image frame according to the bitstream. A mode list including a plurality of intra modes is determined for reconstructing the block unit. At least one of the intra modes is selected from the mode list based on a comparison between the block height and the block width, and removed from the mode list to generate an adjusted list including a plurality of unselected modes. The block unit included in the image frame is reconstructed based on the adjusted list.
Claims20
A method of decoding a bitstream by an electronic device, the method comprising:
- determining a block unit from an image frame according to the bitstream, the block unit having a block height and a block width;
- determining a mode list including a plurality of intra modes;
- selecting at least one of the plurality of intra modes from the mode list based on a comparison between the block height and the block width;
- removing the selected at least one of the plurality of intra modes to generate an adjusted list including a plurality of unselected modes;
- and
- reconstructing the block unit of the image frame based on the adjusted list.
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 unit from an image frame according to the bitstream, the block unit having a block height and a block width;
- determine a mode list including a plurality of intra modes;
- determine an intra prediction indication from the bitstream for indicating a predicted mode of the block unit;
- compare the block height and the block width;
- determine, based on the intra prediction indication and the comparison between the block height and the block width, whether the predicted mode is selected from the plurality of intra modes to determine the predicted mode;
- and
- reconstruct the block unit of the image frame based on the predicted mode.
