Abstract

The invention provides an H.265 ultra-high definition video quality evaluation method. The method comprises the following steps of performing YUV sampling on the original video to obtain an original video sequence; performing video quality evaluation on the original video sequence and the test video sequence, and calculating video quality parameters; and obtaining an evaluation result by the unified video quality evaluation parameters according to the video quality parameters. The method has the advantages that the video quality of the ultra-high-definition video above 4K can be evaluated, andthe limitation of the current video quality evaluation method on the video resolution is broken through.

Description

technical field [0001] The invention belongs to the field of video processing, and in particular relates to an H.265 ultra-high-definition video quality evaluation method. Background technique [0002] The research on video quality assessment (Video quality assessment, VQA) has also received extensive attention in the past 20 years. Video quality evaluation can be divided into subjective evaluation methods and objective evaluation methods. Subjective evaluation is performed by observers to subjectively score the video quality. Generally, the average subjective score (Mean opinion score, MOS) or the average subjective score difference (Differential mean opinion score, DMOS) is used. ), that is, the difference between the evaluation scores of the undistorted image and the distorted image by the human eye, but the subjective evaluation is heavy, time-consuming, and expensive, and it is very inconvenient to use; the objective evaluation method is calculated by a computer based o...
