Abstract:
1. A method of measuring perceptual quality of video, the video being provided over at least one communications channel, the method comprising the steps of: receiving a target video over the at least one communications channel; extracting, from the target video, objective information pertaining to one or more target features of the target video; receiving objective information pertaining to one or more reference features of a reference version of the target video, wherein one or more reference features correspond, respectively, to the one or more target features; providing an objective measurement of perceptual quality of the reference version of the target video based at least on the objective information pertaining to the one or more reference features; providing an objective measurement of a predicted differential mean opinion score (DMOS) between at least a portion of the target video and at least a corresponding portion of the reference version of the target video based at least on the objective information pertaining to the one or more reference features and the information pertaining to the one or more target features; and providing an objective measurement of perceptual quality of the target video, the providing of the objective measurement of perceptual quality of the target video including obtaining a difference between the objective measurement of perceptual quality of the reference version of the target video, and the objective measurement of the predicted DMOS between at least the corresponding portion of the target video and at least the portion of the reference version of the target video.
