Video decoding and encoding methods in geometric segmentation mode, video encoding equipment, and bit stream storage and transmission methods.

Abstract

The invention relates to a method for decoding and encoding video in geometric partition mode (GPM), a video encoding device, and a method for storing and transmitting video streams.The method includes the following steps: partitioning the video block into a first geometric partition and a second geometric partition; obtaining a flag for the first template inatching (TM) for the first geometric partition and a flag for the second TM for the second geometric partition, where the flag for the first TM indicates whether the unidirectional motion of the first geometric partition is filtered by the TM, and where the flag for the second TM indicates whether the unidirectional motion of the second partition is filtered by the TM; obtaining the first unified GPM index for the first geometric partition and the second unified GPM index for the second geometric partition; constructing a list of candidate unidirectional motion vectors (MVs) of the GPM; and generating unidirectional MVs for the first geometric partition and unidirectional MVs for the second geometric partition.
