Embodiment Construction

[0032] Embodiments of the present invention provide a method, device, and system for video quality evaluation, which are used to evaluate video quality, so that video types are not distinguished during video quality evaluation, and the problem of video quality evaluation caused by different video types is solved. complexity and inaccuracy.

[0033] In the video compression encoding and transmission system, for the same video, the amount of encoded output information reflects the amount of video information, and in video quality evaluation, the amount of video information directly determines the video quality evaluation of user experience score, then the amount of encoded output information becomes an important parameter reflecting the video quality.

[0034] Among them, the amount of encoded output information refers to a video source that has not been compressed and encoded. After compressing and encoding a certain compression encoding method or encoder, the compressed encodi...

Abstract

The embodiment of the invention discloses a method for evaluating video quality. The method provided by the embodiment of the invention comprises the following steps: compressing and coding a first video to acquire coding output information content of the first video; acquiring fidelity coding output information content of the first video; and acquiring parameters for evaluating the video quality according to the coding output information content and the fidelity coding output information content, and evaluating the quality of a second video by compressing and coding the first video according to the parameters. The embodiment of the invention also provides a device and a system for evaluating the video quality. The method, the device and the system provided by the embodiment of the invention for evaluating the video quality solve the complexity and inaccuracy of the video quality evaluation brought by different video types by establishing a universal quality evaluation model for the videos of different types.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a video quality evaluation method, device and system. Background technique [0002] With the development of multimedia communication technology, various video services emerge in an endless stream, so the accurate and real-time evaluation of video quality plays a very important role in the fields of video processing, compression and video communication. [0003] Video quality evaluation is to judge the video quality subjectively or objectively, and the methods can be divided into two categories: subjective quality evaluation and objective quality evaluation. [0004] Subjective quality evaluation is to select a group of non-expert testees, let them use various statistical methods to rate the quality of video sequences in a controlled environment, and finally obtain the subjective average score (MOS, Mean Option Score ) and analyze the data ...
