Abstract

The present invention proposes a video image quality evaluation method and evaluation system, which receives the dynamic video captured by the video acquisition terminal; extracts the images to be evaluated in the dynamic video, and divides each of the images to be evaluated into M*N equal-sized image block; calculate the image quality index of the image X to be evaluated, and finally use the image quality index of the image X to be evaluated as the final parameter for evaluating the video image quality. The invention shoots dynamic videos under different conditions and then uploads the dynamic videos. The evaluation system evaluates the quality of video images under different conditions and outputs multi-dimensional video evaluation results, which fairly and objectively reflect the quality of video images.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a video image quality evaluation system and an evaluation method. Background technique [0002] Image and video are the two main forms of media in the current multimedia application system. Image is the basic unit of video, and video is a continuous sequence of images in the time domain. Therefore, the study of images is the foundation of video research. The process of image acquisition, compression, storage and transmission will bring data loss. The traditional subjective method relying on manual observation to evaluate the image quality is not only time-consuming and laborious, but also the evaluation results are affected by factors such as the evaluation environment and the work background of the evaluators. It cannot objectively reflect the quality of the image, so it cannot be applied to the actual multimedia system at all. The "objectification" trend of ima...
