Inter-prediction in geometric partitioning using non-rectilinear non-rectangular partitioning
Exponential partitioning in video codecs improves compression efficiency by dividing video blocks into non-rectangular regions following curved object boundaries, thereby enhancing motion compensation and reducing encoding complexity.

Abstract
To provide an encoder that provides inter prediction in exponential partitioning and a decoder capable of decoding a coded bitstream, as well as a non-transitory computer readable medium.SOLUTION: A decoder includes receiving a bitstream, partitioning a current block into a first region and a second region via an exponential partitioning mode, and determining a motion vector associated with the first region or the second region. The determining includes building a candidate list. The decoder also decodes the current block using the determined motion vector.SELECTED DRAWING: Figure 14
