Abstract: The purpose of stereo video quality assessment (SVQA) is to easily and quickly measure the quality of stereo video, and strive to reach a consensus with human visual perception. Stereo video contains more perceptual information and involves more visual perception theory than 2D image/video,making SVQA more challenging. Aiming at the effect of distortion on the frequency domain characteristics of stereo video, a SVQA method based on frequency domain depth perception is proposed. Specifically, the frequency domain is utilized while minimizing the changes in the existing network structure to realize the in-depth exploration of the frequency domain characteristics without changing the original frame size of stereo video. Experiments are carried out on three public stereo video databases, namely NAMA3DS1-COSPAD1 database, WaterlooIVC 3D Video Phase I database, and QI-SVQA database. From the experimental results, it can be seen that the proposed method has good quality prediction ability, especially on asymmetric compressed stereo video databases.
