Problems solved by technology
[0003] Among the currently published methods for video quality assessment using deep learning, most of them use two-dimensional convolutional neural networks as the main structure to extract the spatial features of video frames, and perform video quality assessment based on spatial features. However, two-dimensional neural networks lack The learning of the timing relationship ignores the inherent motion information of the front and rear frames in the video, resulting in low accuracy of the video quality evaluation results, and it is impossible to effectively guide the video encoding and transmission

Embodiments of the present application provide a video quality assessment method, device, electronic equipment, and storage medium, and relate to the technical field of information processing. The method includes: first obtaining the video to be processed and the reference video corresponding to the video to be processed; then determining the residual video based on the video to be processed and the reference video; The spatio-temporal feature corresponding to the video frame; based on the spatio-temporal feature corresponding to each video frame to be processed and the residual video, determine the quality evaluation result of the video to be processed. The technical solution of this application evaluates the quality through the spatio-temporal features of the residual video and the video to be processed. The residual video reflects the difference between the video to be processed and its reference video, that is, the degree of distortion. The spatio-temporal features of the video to be processed also take time and The feature information is more comprehensive, which improves the accuracy of quality assessment and realizes a more objective assessment of video quality.
Description
technical field [0001] The present application relates to the field of computer technology, in particular, the present application relates to a video quality assessment method, device, electronic equipment and storage medium. Background technique [0002] With the development of multimedia information technology and network communication technology, watching videos online has penetrated into people's daily life. However, compared with pictures, audio, and text, video has a larger amount of data, and the storage and transmission requirements of video data cannot be met without compressing the source video. Due to some unavoidable objective factors in the process of collection, compression, storage, and transmission, the video played on the user terminal has different degrees of distortion, and these distortions will affect the user's viewing experience. Therefore, effective evaluation of video quality is needed to guide the encoding and transmission strategy, so as to improv...
