[0042] The present invention will be further described in detail below in conjunction with specific examples, which are explanations of the present invention rather than limitations.
[0043] In the present invention, the Father's Day block: corresponds to the father node of the tree, and what is processed here is a pixel block, so the corresponding father node is called the father block; various child types correspond to various tree types (see figure 1 ), the child type child1 corresponds to the quadtree division, that is, the horizontal and vertical directions of the corresponding parent block are equally divided, and both child2 and child3 are binary tree divisions, where child2 is 1 / 2 division of the parent block in the vertical direction, and child3 is Make 1 / 2 division of the father block in the horizontal direction, child4 is to make the upper part of the father block in the vertical direction 1 / 4 of the father block, and the lower part is 3 / 4 division; child5 is to do th...
