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 a method for evaluating the quality of H.265 ultra-high-definition video. Background technique [0002] Video quality assessment (VQA) research has also received extensive attention in the past 20 years. Video quality evaluation can be divided into subjective evaluation methods and objective evaluation methods. In subjective evaluation, the observers subjectively score the video quality. Generally, the mean opinion score (MOS) or the differential mean opinion score (DMOS) is used. ), that is, the human eye expresses the difference in the evaluation scores of undistorted images and distorted images, but subjective evaluation is heavy, time-consuming, and expensive, and it is very inconvenient to use; the objective evaluation method is calculated by a computer according to a certain algorithm The image quality index has the characteristics of good consistency, small workload...
