1. A non-transitory computer readable medium storing a bitstream, the bitstream including one or more first parameters according to which a decoder performs a partition process, the one or more first parameters related to a size of an image block,
in the partition process:
the one or more first parameters are compared to one or more thresholds;
in response to the one or more first parameters and the one or more thresholds satisfying one or more determined relationships,
a second parameter is decoded, the second parameter indicating that a plurality of partitions are determined within the image block, the plurality of partitions including a non-rectangular partition;
a motion vector is derived for each of the plurality of partitions; and
the plurality of partitions are decoded using the respective motion vectors after determining the plurality of partitions within the image block when the second parameter indicates that the plurality of partitions are determined within the image block.
