    Abstract: This application provides an example method for processing video or image data. The method includes obtaining a non-overlapped region. The method also includes obtaining a transform block (TB) corresponding to a coding block. The method further includes determining whether the TB cross a border of the non-overlapped region or not. The method also includes, if the TB cross a border of the non-overlapped region, splitting the TB to obtain at least two sub-TBs according to the border of the non-overlapped region.

    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.

    Abstract: This application discloses a construction method and apparatus for a bipartite graph, and a display method and apparatus for a bipartite graph. The construction method includes: searching a computational graph for at least one cross-communication edge corresponding to a first communication node, where the first communication node is one of M communication nodes included in the computational graph, the first communication node corresponds to P predecessor nodes and Q successor nodes, each of the at least one cross-communication edge indicates a communication path between one of the P predecessor nodes and one of the Q successor nodes, and no cross-communication edge passes through the M communication nodes; and cutting cross-communication edges respectively corresponding to the M communication nodes, and performing an aggregation operation to obtain the bipartite graph, where any two of the M communication nodes are connected without an edge in the bipartite graph.
