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: A graph processing method and apparatus are used in the field of data visualization. In this method, first, at least two subgraphs of a first graph are obtained, where each subgraph includes, in the first graph, a plurality of nodes and edges between the nodes; second, the nodes and the edges that are included in each subgraph of the at least two subgraphs are calculated, to calculate respective identifiers of the at least two subgraphs; and third, subgraphs with a same identifier in the at least two subgraphs are combined to generate a second graph; and then the second graph generated through combination is output.

Abstract: A system and method of decoding of a video or picture bitstream implemented by a decoding device are described. The bitstream can include data representing a current video coding layer. Furthermore, when determining that the current video coding layer is the only one layer in the bitstream, the method can include using the identifier of a NAL unit of the current video coding layer as the identifier of the current video coding layer.

Abstract: A partitioning method comprises determining whether a current block of a picture is a boundary block and whether the size of the current block is larger than a minimum allowed quadtree leaf node size; and if the current block is the boundary block and the size of the current block is not larger than the minimum allowed quadtree leaf node size (MinQTSize), applying forced binary tree (BT) partitioning to the current block. A method comprises making a determination that a current block of a picture is a boundary block and that a size of the current block is less than or equal to a minimum allowed quadtree (QT) leaf node size (MinQTSize); and applying, in response to the determination, forced binary tree (BT) partitioning to the current block.
