Construction of Audio-Video Multimedia Database and Multimedia Subjective Quality Evaluation Method

Abstract

The invention provides a construction of an audio-video multimedia database and a multimedia subjective quality evaluation method, by creating a joint quality subjective evaluation audio-video multimedia database specially used for audio and video multimedia, and based on the database, by building audio-video multimedia quality evaluation environment and select the data in the audio and video multimedia database for training to train the testers, test the data to be tested from the audio and video multimedia database for testing, and perform post-data processing on the subjective quality evaluation results obtained from the test to achieve standardization and Streamlined audio-video multimedia subjective quality evaluation.

Description

technical field [0001] The present invention relates to the technical field of subjective quality evaluation, in particular to a method for constructing an audio-video multimedia database, and subjective quality evaluation of audio-video multimedia based on the audio-video multimedia database. Background technique [0002] In recent years, visual quality assessment has attracted the attention of many researchers in the fields of image processing and computer vision. Visual quality assessment can be divided into two categories according to whether there are users to directly evaluate: subjective quality assessment (subjective quality assessment) and objective quality assessment (objective quality assessment). In most visual communication systems, humans are the final recipients of visual media information, so the most reliable evaluation method should be subjective quality evaluation. Subjective quality evaluation usually allows a large number of users to rate the evaluation...

Problems solved by technology

For ordinary visual signals, such as images, the International Telecommunication Union (ITU) proposed in "Methodology for the Subjective Assessment of the Quality of Television Pictures, document Rec.ITU-R BT.500-13, Jan.2012" A subjective image quality evaluation algorithm is proposed, but this method is only suitable for visual signals such as images and videos

Xu Mai et al. proposed a subjective quality evaluation method for panoramic video in "A Subjective Quality Evaluation Method for Panoramic Video, CN201711452823.8", but this method is only suitable for visual signals such as panoramic video

The above two methods are only applicable to visual signals such as images and videos, but not applicable to multimedia signals containing both video and audio

[0004] At present, there is no standardized and streamlined audio-video multimedia subjective quality evaluation method similar to the present invention
