Video quality automatic evaluation system oriented to wireless network and evaluation method thereof

Abstract

The invention relates to a video quality automatic evaluation method and an evaluation method, relating to the evaluation of wireless video communication, which can confirm the evaluation property, reduce needed reference data and reduce calculation complexity, therefore, the evaluation mode is adaptive to the evaluation application facing wireless network. The method comprises: processing content pre-check on the reference video not compressed; according to the average activity of each activity region, dividing the check on the video characters into high and low activity region character checks, to attain the check parameters representing the spatial domain and time domain characters which express the characters of the video sections in each activity region; weighting the check parameters of the spatial domain and time domain characters of each activity region to build the spatial domain and time domain character parameters of the whole video, realizing the projection between the check parameters and the subjective quality expression according to a preset video quality evaluation database, to realize the automatic evaluation on the video quality facing wireless network.

Description

technical field The invention relates to an evaluation of wireless video communication, in particular to an evaluation method of a wireless network-oriented video quality automatic evaluation system. Background technique The overall development trend of the communication network is: "Broadband", "Wireless" and "Mobilization". With the development of broadband wireless communication technology and the popularization of Internet services, the business forms carried by wireless networks are also becoming more and more abundant, showing the development trend of "multimedia", "entertainment" and "personalization". In the next few years, voice (or small traffic data)-based business forms on traditional telecom networks will be gradually replaced by video-based multimedia services. People will no longer be satisfied with transmitting text and voice through wireless networks, but also hope to see pictures and scenes of life through wireless networks, such as mobile theater, mobile ...
