Embodiment Construction

[0013] An embodiment of the present invention proposes a down-sampled video frame reconstruction method, which includes the following steps: acquiring data to be decoded corresponding to the video frame to be decoded. Wherein, the data to be decoded refers to data obtained after encoding. The decoding end obtains the data to be decoded corresponding to the video frame to be decoded, and obtains the decoded video frame by decoding the data to be decoded.

[0014] Secondly, the downsampling information corresponding to the video frame to be decoded is obtained from the data to be decoded. Wherein, by acquiring the flag bit corresponding to the preset position in the data to be decoded, the downsampling information corresponding to the video frame to be decoded is obtained through the flag bit. The downsampling information includes at least one of a downsampling ratio and a downsampling method.

[0015] Then, the data to be decoded is decoded according to the downsampling infor...

Abstract

The invention discloses a video frame reconstruction method based on down-sampling. The method includes the steps of acquiring to-be-decoded data corresponding to a to-be-decoded video frame, acquiring down-sampling information corresponding to the to-be-decoded video frame from the to-be-decoded data, and decoding the to-be-decoded data according to the down-sampling information corresponding tothe to-be-decoded video frame to obtain a corresponding decoded video frame. By acquiring the down-sampling information corresponding to the to-be-decoded video frame from the to-be-decoded data and carrying out decoding according to the down-sampling information, decoding support is provided for the to-be-decoded data obtained by carrying out coding through adaptive selection of down-sampling information.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a video frame reconstruction method based on downsampling. Background technique [0002] Information coding is the process of assigning codes to information elements during information processing in order to facilitate the storage, retrieval and use of information. That is to use different codes to establish a one-to-one correspondence with the basic unit components in various information. Information coding must be standardized and systematic, and designing a reasonable coding system is an important factor for the vitality of the relationship information management system. Under the condition of limited bandwidth, traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. When encoding all video frames indiscriminately, some video frames may have poor quality. question. Contents of the invention [00...
