The invention discloses a video coding method, a video decoding method and related devices. The video coding method comprises the following steps: acquiring a first video frame in a video stream, wherein the first video frame comprises a plurality of first pixel blocks; determining a bit plane VJND threshold block of each of the first pixel blocks according to a view just noticeable difference VJND model; for each first pixel block, coding information of a target matching block according to a preset coding format to obtain first coding data of the first pixel blocks, wherein the information of the target matching block is determined according to a bit plane VJND threshold block of the first pixel blocks; and based on the first coding data of the plurality of first pixel blocks, determining the coding data of the M-layer bit plane of the first video frame. By adopting the video coding method, the video decoding method and the related devices provided by the invention, the transmission data volume of the coded data of the first video frame can be reduced, so that the data transmission bandwidth is reduced.
Description
technical field [0001] The present application belongs to the field of image processing, and in particular relates to a video encoding method, a video decoder and related devices. Background technique [0002] The near-eye display is a new type of display that is located near the human eye and is enlarged by an optical system to form a field of view. It can display scenes with wearables, such as helmets and glasses used in the field of virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, AR). In order to further improve the user experience, the near-eye display should have higher resolution and refresh rate, and the device should be miniaturized, lightweight, and easy to wear. High resolution and high refresh rate mean that a large amount of data will be transmitted and stored, which not only doubles the pressure on bandwidth transmission, but also leads to a waste of hardware resources. To solve this problem, the scheme of video data compression us...
