Method and device for assessing video quality

Abstract

The invention discloses a method and a device for assessing video quality. The method comprises the steps of: grouping to-be-accessed videos based on video contents, wherein each video group comprises at least two to-be-accessed videos; based on a video grouping result, generating address information pointing at a playing interface comprising the at least two to-be-accessed videos, so as to synchronously play the at least two to-be-accessed videos based on the address information, and obtaining a subjective assessment result of each to-be-accessed video in the at least two to-be-accessed videos; respectively obtaining at least one assessment parameter of the to-be-accessed videos, wherein the at least one assessment parameter represents the quality of the videos; based on the at least one assessment parameter, and a weight coefficient preconfigured for each assessment parameter, obtaining an objective assessment result of the to-be-accessed videos; and based on the subjective assessment result and the objective assessment result of the to-be-accessed videos, obtaining a quality assessment result of the to-be-accessed videos.

Description

technical field [0001] The invention relates to Internet communication technology, in particular to a video quality evaluation method and device. Background technique [0002] With the vigorous development of the Internet and multimedia technology, watching videos online has become one of the main entertainment methods in daily life. Users' pursuit of viewing experience is also increasing with the popularity of online videos. Video quality is the key to affecting users' viewing experience factors, so how to effectively evaluate the quality of video is of great significance. [0003] At present, there are mainly two ways to evaluate video quality: subjective quality evaluation and objective quality evaluation. Among them, subjective quality evaluation usually needs to be carried out under restricted environmental conditions, which is difficult to implement and is not convenient for evaluating a large number of videos. However, the objective quality assessment is carried out ...

[0003] At present, there are mainly two ways to evaluate video quality: subjective quality evaluation and objective quality evaluation. Among them, subjective quality evaluation usually needs to be carried out under restricted environmental conditions, which is difficult to implement and is not convenient for evaluating a large number of videos.

However, the objective quality assessment is carried out using the full reference model, which requires the original video for comparison, the scope of application is limited, the adaptability is poor, and the video resolution is not comparable after scaling
