Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The specific implementation process can be as follows: firstly build based on the Android development environment, make a video player based on Androidyuv by calling the SDL third-party library, design and implement the evaluation system, design the interface for subjective evaluation of video quality, including user login system and real-time update of the database , The scene selection interface is autonomous and random, the video playback interface, and the scoring function are limited. The objective evaluation only allows administrators to log in, so the administrator identity authentication is set up, and the administrator information needs to be verified. When it matches the information in the database, it will enter the objective evaluation system, otherwise it cannot be entered. Administrators can view the data of subjective evaluation, perform...

Abstract

The invention relates to a video quality evaluation system comprising a video quality objective evaluation system and a video quality comprehensive evaluation system. The video quality objective evaluation system comprises a peak value signal-to-noise ratio computing unit, an edge structure similarity computing unit, a sharpness computing unit, a space-time threshold computing unit, and an objective evaluation data processing unit. The objective evaluation data processing unit comprises an original data evaluation matrix constructing unit, a standard matrix constructing unit, and a weight computing unit. The video quality comprehensive evaluation system comprises an subjective result receiving module, an objective result receiving module, a second original data evaluation matrix constructing unit, a second standard matrix constructing unit, and a second weight computing unit. The video quality evaluation system effectively improves the accuracy of video evaluation results and achieves high-efficient evaluation.

Description

technical field [0001] The present invention is a video quality evaluation system applied to mobile terminals. It is mainly aimed at analyzing the video of the tablet computer of the Android system. The video quality evaluation method is used for subjective evaluation and objective evaluation of the video, and the video quality is efficiently evaluated, so that the video quality can be controlled. And improve the quality of digital video, better provide guidance for mobile terminal manufacturers. Background technique [0002] Nowadays, in the development of video from analog to digital, various differences will occur in the process of video sampling, compression, transmission and reconstruction, which will cause different degrees of video distortion. At present, most evaluations of video quality are carried out based on PCs, but there are relatively few research fields based on mobile terminals. How to efficiently evaluate video quality based on mobile terminals is the focus...
