Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] figure 1 It shows that Embodiment 1 of the present invention provides a video quality assessment method, including:

[0052] S11. Obtain multiple evaluation parameters of the video to be evaluated.

[0053] In this step, it should be noted that the method described in the embodiment of the present invention is a non-reference video quality evaluation method, so it does not require additional bandwidth to transmit the original video and related information, and only needs to obtain the parameter information of the video to be evaluated That's it.

[0054] In the embodiment of the present invention, multiple evaluation parameters may include resolution, playback de...

Abstract

The invention provides a video quality evaluation method and device; the method comprises the following steps: acquiring multiple evaluation parameters of a to-be-evaluated video; calculating according to the evaluation parameters and obtaining a corresponding influence factor; and obtaining an evaluation value according to the influence factor and displaying the evaluation value. According to thevideo quality evaluation method and device provided by the embodiment of the invention, multiple evaluation parameters of the to-be-evaluated video are obtained, the corresponding influence factor isobtained according to the multiple evaluation parameters, and then the evaluation value is obtained and displayed according to the influence factor, so that manual participation is not needed, original video contrast reference is not needed, and extra transmission bandwidth is not needed; only a single terminal is required to obtain less reference data, so that the calculation amount is reduced,and the VMOS value can be quickly and reasonably calculated; meanwhile, the evaluation method and device are not only suitable for video services and also applicable to multimedia service evaluation carried by other LTE and RTP protocols.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a reference-free video quality evaluation method and device. Background technique [0002] Video quality assessment methods can be divided into subjective assessment and objective assessment. Since people are the final recipients of video services, the subjective evaluation method is undoubtedly the most pertinent quality evaluation, which can directly reflect the quality of video services. However, this evaluation method also has time-consuming, high cost, and individual differences. However, it is not suitable for large-scale practical applications due to its disadvantages such as non-reliability, inability to perform real-time monitoring, and inability to locate quality problems. Therefore, intelligent analysis of distorted video by designing a mathematical model to calculate an objective quality evaluation method for video quality has become a current intern...
