INCREASING THE DEPTH OF A MULTIPLE TYPE TREE FOR PROCESSING IMAGE BORDERS Russian patent published in 2023 - IPC H04N19/70 

FIELD: audio data processing.

SUBSTANCE: claimed solution provides for the possibility of dividing the image into coding tree units (CTUs), including a non-boundary CTU with a size in the horizontal and vertical direction and a boundary CTU having a part inside the image limited by a horizontal or vertical border of the image, while the part is smaller than the size in the direction perpendicular to the border of the image; and separating the non-boundary CTU and the boundary CTU hierarchically into respective coding units, wherein the hierarchical division of the non-boundary CTU includes a multi-type split with a maximum non-boundary multi-type split depth, the multi-type split being a split with a split direction being a vertical or horizontal direction.

EFFECT: increase in the flexibility of separation of boundary CTUs.
