Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the video quality evaluation method according to an embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The invention proposes an effective video quality evaluation method based on random graph and statistical topology. The method provided by the present invention does not require observers to do a complete number of comparisons, that is, it does not need any two videos to be compared once; on the contrary, it is hoped that they can provide an evaluation result close to a complete comparison by only doing some comparisons, In this way, the purpose of saving time and labor is achieved, especially for the situation where the number of videos to ...

Abstract

The invention provides a video quality evaluation method comprising the following steps: 10), taking each video to be evaluated as one node on a graph so as to construct the graph, determining the number of borders needing to be added on the graph according to the total number of the videos, wherein the comparative result of paired compared videos of an observer corresponds to one border of the graph; 20), mapping the comparative result on the graph according to the number, taking the graph as the input of Hodge decomposition; and 30), obtaining the quality score of each segment of video according to the Hodge decomposition. With the adoption of the above method provided by the invention, the operation is simple and both time and manpower are saved without reducing the accuracy of the video quality evaluation; in addition, the video quality evaluation method is beneficial for network crowdsourcing.

Description

technical field [0001] The present invention relates to the field of information engineering, in particular to the field of image and video analysis and processing. Background technique [0002] With the advent of the digital age, multimedia products such as images and videos play an increasingly important role in people's daily lives. In all fields of video processing: acquisition, display, storage, transmission, compression, etc., quality evaluation is required. The research on quality evaluation technology has become one of the important basic research topics in information engineering, which has both important theoretical significance and extensive application background. [0003] Generally, video quality evaluation methods are divided into subjective evaluation and objective evaluation. Among them, objective evaluation methods are mainly divided into three categories: full reference evaluation, partial reference evaluation, and no reference evaluation. However, they ...
