Abstract (en)

[origin: WO2021037053A1] The present disclosure discloses a method of coding implemented by a decoding device, comprising: obtaining a bitstream; obtaining an aspect ratio of a current block; obtaining a context model index for the current block according to the aspect ratio; obtaining, according to the context model index of the current block, a value of a geometric partition flag for the current block from the bitstream, wherein the geometric partition flag of the current block indicates whether a geometric partition mode is used or not for the current block; and decoding the current block according to the value of the geometric partition flag.
