Abstract

The invention provides a video and audio joint quality evaluation method. The method comprises the following steps: predicting video quality by using a video quality evaluation model to obtain a videoprediction quality score Qv and a video prediction quality feature fv; predicting the audio quality by using an audio quality evaluation model to obtain an audio prediction quality score Qa and an audio prediction quality feature fa; normalizing the video prediction quality score Qv and the audio prediction quality score Qa respectively to obtain a normalized video prediction quality score and anaudio prediction quality score, fusing the normalized video prediction quality score and the audio prediction quality score, or fusing the video prediction quality feature fv and the audio predictionquality feature fa to obtain a predicted video and audio joint quality score Qav or feature fav. Meanwhile, the invention provides a video and audio joint quality evaluation device. By utilizing themethod and the device provided by the invention, the overall experience quality of the audio and the video can be effectively evaluated.

Description

technical field [0001] The present invention relates to the technical field of multimedia quality evaluation, in particular to a video and audio joint quality evaluation method and device. Background technique [0002] In recent years, multimedia quality assessment has attracted the attention of many researchers in the fields of audio processing and video processing.
