Abstract (en)

[origin: WO2011070158A1] Method of estimating the perceived quality of a video sequence at a maximum spatial resolution and a maximum temporal resolution, and at a lower spatial resolution and/or temporal resolution, said method being characterized in that it comprises at least a first step of filtering said video sequence at the lower temporal resolution and/or the lower spatial resolution so as to produce a filtered video sequence at the maximum spatial and temporal resolutions, a second step of determining a reference sequence that is, at most, equal to the content of said video sequence at the maximum spatial and temporal resolutions, and a third step of calculating a metric of perceived quality of said video sequence at the lower temporal resolution and/or the lower spatial resolution.
