Systems and methods for image coding

A system for intra prediction, comprising:

• at least one storage device including a set of instructions;
• and
• at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is directed to cause the system to:
• obtain a target block to be encoded in a target image;
• determine a final most probably mode (MPM) list of the target block based on at least one of
• (a) first intra-prediction modes configured to encode two or more adjacent blocks of the target block,
• (b) a width and a height of the target block,
• (c) statistical information of second intra-prediction modes configured to encode a plurality of first encoded blocks associated with the target block, and
• (d) texture features of a plurality of second encoded blocks associated with the target block;
• obtain a code word of a target intra-prediction mode of the target block;
• obtain the target intra-prediction mode by decoding the code word of the target intra-prediction mode based on the final MPM list;
• and
• decode the target block based on the target intra-prediction mode.

A method for intra prediction implemented on a machine having one or more storage devices and one or more processors, the method comprising:

• obtaining a target block to be encoded in a target image;
• determining a final most probably mode (MPM) list of the target block based on at least one of
• (a) first intra-prediction modes configured to encode two or more adjacent blocks of the target block,
• (b) a width and a height of the target block,
• (c) statistical information of second intra-prediction modes configured to encode a plurality of first encoded blocks associated with the target block, or
• (d) texture features of a plurality of second encoded blocks associated with the target block;
• determining, based on the final MPM list, a target intra-prediction mode corresponding to the target block;
• and
• encoding, based on the target intra-prediction mode, the target block.
