Embodiment Construction

[0037] In various embodiments herein, each device or system can reduce the bandwidth occupied by storing and transmitting a curved surface video. In some embodiments, the curved video may be a picture projected on any smooth surface (eg, at least part of a sphere or ellipsoid). A curved surface video includes multiple frames of curved surface images, wherein the contents of the curved surface images include contents captured in different directions at the same moment. Therefore, a curved video can cover a larger field of view. For example, a spherical video (or 360-degree panoramic video) includes multiple frames of spherical images that can cover a field of view of a 360-degree panoramic view. In some embodiments, a spherical video can have a horizontal field of view of 360 degrees and a vertical field of view of 180 degrees, usually presented in a three-dimensional spherical form. In the following, a spherical video is taken as an example to describe a curved video. It wi...

Abstract

The video decoding method includes: dividing a block to be decoded in an image to be decoded into at least two prediction blocks, the at least two prediction blocks are respectively located in at least two partitions of the image to be decoded, wherein the image to be decoded It is a planar image formed by splicing a plurality of polygons at least partially mapped onto a polyhedron surface, and at least two partitions of the image to be decoded correspond to at least two polygons on the polyhedron surface; different reference blocks are used Predict the at least two prediction blocks respectively.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, to a video encoding method and device, and a video decoding method and device. Background technique [0002] In recent years, the volume of video content has been growing due to the prevalence of various types of portable, handheld or wearable devices. For example, virtual reality or augmented reality can be integrated into different head mounted devices (HMD). As the form of video content becomes more and more complex, the storage and transmission of video content becomes more and more challenging. For example, there is a need to reduce bandwidth for video storage and transmission. Contents of the invention [0003] Embodiments of the present invention provide a video encoding method and device, and a video decoding method and device. [0004] In a first aspect, a video coding method is provided, including: [0005] Dividing a block to be decoded in the image ...
