Title: DEVICES AND METHODS FOR VIDEO CODING USING SEGMENTATION BASED PARTITIONING OF VIDEO CODING BLOCKS
Abstract:
The invention relates to an encoding apparatus for processing a video signal comprising a plurality of frames dividable into video coding blocks. A first video coding block of a current frame of the video signal is partitioned into a first segment associated with a first segment motion vector relative to a first reference frame of the video signal and a second segment. The first video coding block is associated with a plurality of virtual partitions. Each virtual partition is associated with a respective subset of the plurality of video coding blocks of the current frame. Each video coding block of the respective subset neighbors the first video coding block and is associated with a motion vector. An encoding processor encodes, for each of the virtual partitions the first segment motion vector on the basis of at least one motion vector of the neighboring video coding blocks associated with the selected virtual partition for encoding the first video coding block. The virtual partition is selected based on a respective performance measure associated with the encoding of the first segment motion vector. A virtual partition identifier of the selected virtual partition and coding information including the encoded first segment motion vector are generated.
