1. A picture partitioning method, comprising:
determining a split mode of a current node that comprises a luma block and a chroma block;
determining, based on the split mode of the current node and a size of the current node, that the chroma block of the current node is not further split; and
splitting, based on the split mode of the current node, the luma block of the current node;
wherein the chroma block of the current node is not further split in accordance with one or more determinations taken from the group consisting of:
a width of the current node is equal to twice a threshold and the split mode of the current node is a vertical binary split,
a height of the current node is equal to twice a threshold and the split mode of the current node is a horizontal binary split,
a width of the current node is equal to four times a threshold and the split mode of the current node is a vertical ternary split,
a height of the current node is equal to four times a threshold and the split mode of the current node is a horizontal ternary split, and
a width of the current node is equal to twice a threshold and the split mode of the current node is a quad split.
