Problems solved by technology

[0004] Under the condition of limited bandwidth, traditional encoders encode image frames indiscriminately, which may cause poor image quality in some scenes. When encoding all image frames indiscriminately, some image frames may have poor quality. question

Embodiment Construction

[0012] In one embodiment of the present invention, an image frame decoding method based on environment information is proposed, which may specifically include the following steps: firstly, obtain encoded data corresponding to an image sequence to be decoded. The image sequence to be decoded is an image sequence that needs to be decoded. A sequence of images to be decoded may include multiple image frames to be decoded. The image sequence to be decoded may be an image sequence acquired in real time, or a pre-stored image sequence to be decoded. It can be understood that at the encoding end, what is encoded is the encoded data corresponding to the input image sequence, and when the encoded data is transmitted to the decoding end, the received encoded data is the encoded data corresponding to the image sequence to be decoded.

[0013] Secondly, the target image sequence decoding mode corresponding to the image sequence to be decoded is acquired, and the image sequence decoding m...

Abstract

The invention relates to an image frame decoding method based on environmental information. When the method is adopted to decode the image; obtaining coded data corresponding to the to-be-decoded image sequence, and obtaining a target image sequence decoding mode corresponding to the to-be-decoded image sequence, the image sequence decoding mode comprising a fixed code rate decoding mode or a cross code rate decoding mode, and decoding the coded data corresponding to the to-be-decoded image sequence according to the target image sequence decoding mode to obtain a corresponding decoded image frame sequence. Therefore, when decoding is carried out, decoding can be flexibly carried out according to the target image sequence decoding mode corresponding to the to-be-decoded image sequence, andan accurate decoded image frame can be obtained.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image frame decoding method based on environment information. Background technique [0002] Image coding refers to the technology of representing the image or the information contained in the image with a small number of bits under the condition of satisfying a certain quality. In information theory terminology, it is called source coding. It is widely used in image data compression, image transmission and feature extraction. The basic principle is: reduce redundant information in the image to shorten the time for transmitting useless information, use the inherent statistical characteristics of the image to encode; use people's visual psychological characteristics to encode. Common methods include predictive coding, transform coding and hybrid coding. [0003] In the application, coding methods of different types of structure should be considered. Adding satellite ...
