Abstract

The embodiment of the invention discloses a video quality identification method and system, and the method comprises the steps: obtaining the playing information of a target video, and judging whetherthe target video is a suspected low-quality video or not based on the playing information; After determining that the target video is a suspected low-quality video, identifying at least one of audioinformation and picture information of the target video to judge whether the target video has specified quality characteristics or not; Obtaining a judgment threshold value associated with the specified quality feature, and judging whether the specified quality feature belongs to an abnormal quality feature or not based on the judgment threshold value; And determining whether the target video is alow-quality video based on a judgment result for the specified quality feature. According to the technical scheme provided by the invention, the video quality can be more comprehensively evaluated.

Description

technical field [0001] The present application relates to the field of Internet technologies, and in particular to a video quality identification method and system. Background technique [0002] With the continuous development of Internet technology, more and more video playback platforms have emerged. The quality of the video on the video playback platform usually determines whether the video playback platform receives the attention of users. Therefore, video playback platforms usually identify the quality of videos to remove videos with lower quality. [0003] At present, when identifying video quality, it is usually to evaluate indicators such as blurriness, clarity, and coding rate of the video. Specifically, the videos to be evaluated can be grouped, and then through subjective scoring and objective scoring, the indicators such as video blur, clarity, and encoding rate can be judged, and finally low-quality videos can be comprehensively determined. [0004] However, ...
