The processing circuitry is configured to compare a value of a dimension of a current block of the stored video data to a ei © value of a corresponding dimension of a neighboring block of the current block to obtain a relative dimension value. The processing ON circuitry is further configured to determine, based on the relative dimension value, that the current block is to be partitioned according C to a prediction tree (PT) portion of a multi-type tree-based partitioning scheme. The PT portion comprises partitioning according to one ---- of a binary tree structure or a center-side triple tree structure. The processing circuitry is further configured to partition, based on the GC determination, the current block according to the PT portion, to form a plurality of sub-blocks. 1-1 0 ei O [Continued on next page] WO 2018/049020 Al MIDEDIMOMMIDIREEMOOVIEM01101011MOVOIMIE (74) Agent: SRINIVASAN, Sriram; Shumaker & Sieffert, PA., 1625 Radio Drive, Suite 100, Woodbury, Minnesota 55125 (US).
