Embodiment 1

[0154] Embodiment 1: a kind of segmentation method, comprises:

[0155] Determine whether the current block of the image is a boundary block;

[0156] If the current block is a boundary block, determine whether the size of the current block is greater than the minimum allowed quadtree leaf node size;

[0157] If the size of the current block is not larger than the allowed minimum quadtree leaf node size, apply a forced binary tree (binary tree, BT) split to the current block.

Embodiment 2

[0158] Embodiment 2: According to the segmentation method described in Embodiment 1, the forced binary tree segmentation is recursive horizontal forced binary tree segmentation when the current block is located on the lower boundary of the image, or when the current block is located on the lower boundary of the image On the right boundary of , it is a recursive vertical forced boundary split.

Embodiment 3

[0159] Embodiment 3: According to the segmentation method described in Embodiment 1 or 2, the forced binary tree segmentation includes: recursively segmenting the current block by horizontal forced boundary segmentation until the sub-partitions of the current block are directly located at the The lower boundary; recursively split the sub-partitions by vertically enforced boundary segmentation until a leaf node is completely directly on the right boundary of the image, and vice versa.

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 on the current block. A method comprises making a determination that the current block of the picture is the boundary block and the 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 on the current block.

Description

[0001] Cross References to Related Applications [0002] This application requires the U.S. patent application No. 62 / 697,274 filed by Futurewei Technology Co., Ltd. on July 12, 2018, the title of the invention is "A Video Encoder, A Video Decoder and Corresponding Methods" Priority to Provisional Patent Application and U.S. Provisional Patent Application No. 62 / 818,996, filed March 15, 2019, entitled "Boundary Block Partitioning in Video Coding," The contents of both applications are incorporated herein by reference. technical field [0003] The embodiments of the present application generally relate to the field of video decoding, and in particular, relate to division and segmentation of coding units. Background technique [0004] Large amounts of video data need to be described even in the case of short videos, which can cause difficulties when the data is to be sent or otherwise transported over a communication network with limited bandwidth capacity. Therefore, video ...
