Abstract: The present disclosure relates to encoding a decoding video employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for said region. Moreover, a set of parameters specifies luminance within the texture region (1001) by fitting the texture region samples to a two-dimensional polynomial function of the patch determined according to the set of parameters (1040); and/or motion within the texture region by fitting motion estimated between the texture region of the video picture and an adjacent picture to a two-dimensional polynomial The texture patch and the first set of parameters are then included into a bitstream which is output of the encoder and provided in this way to the decoder which reconstructs the texture based on the patch and the function applied to the patch.

Abstract: The present disclosure relates to motion vector determination employing template matching. At first, an initial motion vector is obtained. If the initial motion vector points to a position which is fractional and thus, requires interpolation from the integer sample positions, the initial motion vector is rounded to a closest integer sample position. The rounded position is then used to define the search space for the template matching to define a refinement of the initial motion vector.

Abstract: An encoding apparatus and a decoding apparatus for processing a video signal 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.

Abstract: The present disclosure relates generally to video coding and picture partitioning methods. In particular, the disclosure is concerned with relations between partition constraint elements, by setting partitioning rules for different picture partitioning methods. The disclosure provides devices and corresponding methods for generating or processing a bitstream including encoded pictures, particularly for setting and including partition constraint element into the bitstream. One of the devices is configured to determine a minimum luma size of a leaf block resulting from quadtree splitting (MinQtSizeY), determine a maximum luma size of a coding block where partitioning using a binary tree splitting is allowed (MaxBtSizeY) based on the MinQtSizeY, and include information for the determined MinQtSizeY into the bitstream.
