Abstract

The present invention discloses a video image encoding and decoding method, comprising: obtaining a first-level sub-region code stream corresponding to a target sub-image of a panoramic image, the first-level sub-region code stream includes N second-level sub-region code streams, where N is Positive integer; analyze the first-level sub-region code stream to obtain the reconstructed image. When the out-of-loop filter flag indicates that the reconstructed image should be out-of-loop filtered, the reconstructed image will be out-loop filtered across the boundary of the sub-region to obtain the filtered reconstructed image ; Adjust the position of at least one sub-region in the N sub-regions in the filtered reconstructed image, so as to obtain an image without sub-region boundaries. The embodiment of the present invention also provides a terminal device and a server. Adopting the embodiment of the present invention is beneficial to solve the problem of discontinuous content of video images with continuous content due to division of area coding.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for encoding and decoding video images. Background technique [0002] Virtual reality (Virtual Reality, VR) / 360-degree panoramic video has brought people a new viewing method and visual experience. In a VR video application scenario, all content viewed by a user at a certain moment is called a "viewpoint". The image signal of VR panoramic video can be virtualized as a spherical signal. [0003] Since the image content information at each moment (each moment corresponds to a viewing angle) when the user watches only accounts for a small part of the entire panoramic image, the entire video screen can be divided, and the code stream corresponding to the sub-area corresponding to the current viewing angle can be processed. The transmission enables the presentation of the perspective without the need to transmit the entire image. [0004] In order to save encodin...
