No-Reference Quality Assessment of Stereoscopic Video Based on Deep Frequency Perception

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.
