Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] The present invention provides a kind of video quality assessment method based on short-term memory and user expectation, comprises the following steps:

[0043] Step S1: Representing different durations of short-term memory formation through pre-experience videos of different durations, conducting a first subjective experiment, and obtaining first subjective data;

[0044] Step S2: Preprocessing the first subjective data obtained, and analyzing the experimental results of the first subjective experiment;

[0045] Step S3: Based on the analysis results of the first subjective experiment, design and conduct a second subjective experiment to obtain the second subjective data of different user expectations on the subsequent video experience formed after the impact of short-term memory, where user expectations are represented by the intrinsic quality...

Abstract

The invention relates to a video quality evaluation method based on short-term memory and user expectations. Through subjective experiments, different durations of short-term memory formation and video experience data of user expectations generated after short-term memory are obtained. Finally, through data analysis and mathematical modeling, the evaluation model of memory formation time and user expectations on video experience quality is obtained. The present invention considers short-term memory, user expectations and the influence of video quality, and can obtain more accurate video quality evaluation.

Description

technical field [0001] The invention belongs to the field of video quality evaluation, in particular to a video quality evaluation method based on short-term memory and user expectations. Background technique [0002] With the rapid development of the Internet, major online video platforms such as YouTube and Netflix are becoming more and more popular. Since watching online videos is easily affected by factors such as the network, the quality of video playback may fluctuate, thereby bringing different quality of experience to users. Therefore, in order to provide better services to online video users, video providers need to monitor and evaluate video quality in real time. Many video quality assessment methods are based on image quality assessment methods. But unlike images, video has a time domain, and the quality of a video may fluctuate at different times, while the quality of an image is fixed. Therefore, when studying video real-time QoE, it is necessary to take into...
