The role of temporal aspects for quality assessment

For quality assessment, videos are often considered as series of images with, at best, a motion component. To study the role of temporal aspects in quality, we compare the perceived quality of two versions of a mosquito noise correction algorithm: one purely spatial and the other spatio-temporal. We set up a paired-comparison experiment specially adapted to the temporal aspects of video quality. Results prove the existence of a purely temporal aspect in video quality perception.
