Methods and apparatus of geometry partition mode with subblock modes

An apparatus for video coding, the apparatus comprising one or more electronics or processors arranged to:

• receive input data associated with a current block, wherein the input data comprise pixel data to be encoded at an encoder side or coded data associated with the current block to be decoded at a decoder side;
• partition the current block into a first region and a second region along a partition line;
• derive a target candidate list comprising one or more GPM (Geometry Partition Mode) subblock candidates corresponding to one or more GPM subblock modes for one of the first region and the second region;
• and
• encode or decode said one of the first region and the second region using the target candidate list comprising said one or more GPM subblock candidates.

A method of video coding, the method comprising:

• receiving input data associated with a current block, wherein the input data comprise pixel data to be encoded at an encoder side or coded data associated with the current block to be decoded at a decoder side;
• partitioning the current block into a first region and a second region along a partition line;
• determining an inherited LIC (Local Illumination Compensation) flag by inheriting a reference LIC flag associated with a reference block of the current block;
• encoding or decoding the first region and the second region using coding information comprising the inherited LIC flag and a candidate list including one or more GPM merge candidates.
