Perceptual quality assessment of nighttime video

The quality of nighttime videos is important for consumer photography and monitoring of video clearness. However, little work has been done on the study of nighttime video quality assessment. In this paper, to the best of our knowledge, we explore the study on the nighttime video quality assessment for the first time. First, we build a real-world nighttime video quality assessment database (NVQA) containing 200 videos with abundant content and diverse distortion. Additionally, we carry out subjective tests to rate all nighttime videos in the NVQA database. Thereafter, we proposed a blind nighttime video quality assessment model based on feature fusion and conducted experiments to evaluate the performance and efficiency of our proposed model. The experiment results demonstrate that our model outperforms most traditional methods.
