Abstract

The invention discloses a machine-oriented universal coding method, including: compression coding stage: for different machine intelligence analysis tasks, adopt independent task mode and / or multi-task sharing mode to compress corresponding video or image data to obtain corresponding feature information ; Put the feature information into the code stream corresponding to the video or image data, and at the same time combine the compression mode to give the label information required in the decoding, so as to obtain the feature code stream; Decoding stage: read the header information of the feature code stream, according to the The annotation information determines the compression mode used in the compression stage, so that the feature information is read in a corresponding way, and then the feature information is used as the input of the machine intelligence analysis task to obtain the analysis result. This method can realize the encoding of video / image feature information required for each task, thereby improving the efficiency of intelligent task analysis, reducing transmission pressure, supporting edge analysis and computing, and other possible future needs.

Description

technical field [0001] The invention relates to the technical field of video / image coding, in particular to a machine-oriented general coding method. Background technique [0002] Existing video / image compression standards are mainly aimed at compression for the human eye, and as machine learning algorithms mature, machine intelligence analysis tasks are gradually being applied to various fields of human social life and production, such as smart factories, smart Cities, smart transportation and more. The realization of this series of applications is often accompanied by the analysis of a large amount of video / image data. Using the traditional human-eye-oriented compression method, the code stream needs to be decoded before analysis to obtain a complete video / image, which will not only bring a heavy burden to transmission, but also It will also cause delays, resulting in poor user experience, analysis errors and even more serious problems. At the same time, with the develop...
