In addition, to manipulate the temporal variation of distortions, we propose a novel temporal pooling method using an attention model. ...
Incorporating spatio-temporal human visual perception into video quality assessment (VQA) remains a formidable issue. ...

Its purpose is not to describe a particular model or system, but rather to summarize and to provide pointers to up-to-date knowledge of important characteristics of the human visual system, to explain ...
Simple error measures such as RMSE or PSNR, albeit popular, ignore this important fact and are only a mediocre predictor of perceived quality. ...
Alternatively, the distortion can be computed locally for every pixel, yielding a perceptual distortion map for better visualization of the temporal and spatial distribution of distortions. ...

The perception of in-the-wild video quality without reference is mainly challenged by hybrid distortions with dynamic variations and the movement of the content. ...
Objective VQA methods can mimic the human visual system (HVS), distinguish distortion in the video, and thus reasonably perceive the quality of the video. ...
