Abstract

The embodiment of the invention belongs to video processing and relates to a video quality evaluation method. The method comprises the following steps: extracting video images from an original video frame by frame; generating test labels for the video images according to a frame extraction sequence, and integrating the test labels into the video images to obtain test videos; storing the test labeland the storage path of the video image in a database to obtain an image index; inputting the test video into an audio and video system; when an output video is received from the output end of the audio and video system, querying a video image corresponding to the output image according to the output label of the output image in the output video and the image index to obtain a comparison image; and calculating the similarity between the output image and the comparison image to obtain a quality evaluation result. The invention further provides a video quality evaluation device, computer equipment and a storage medium. In addition, the invention also relates to the blockchain technology, and the original video is also stored in the blockchain. By adopting the method, the technical problemsof low accuracy of an evaluation result and relatively low result reliability in the prior art are solved.

Description

technical field [0001] The present application relates to the field of video processing, in particular to a video quality assessment method, device, computer equipment and storage medium. Background technique [0002] At present, the objective evaluation of video quality is mainly divided into two categories: with reference and without reference. The difference lies in whether the evaluation of the video to be tested depends on the information of the original video. With reference evaluation, the original video must be available, and there are some restrictions on the usage scenarios. But the accuracy is relatively high. In the prior art, there is a method of comparing the similarity with the video segment at the same position of the video to be tested by setting at least one frame of calibration frame image in the video to be tested for subsequent acquisition of the video segment in the comparison video. During the transmission of video sequences, there are usually phenome...
