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: obtaining one or more target feature training vectors, the one or more target feature training vectors representing one or more target training features of at least one target training video; obtaining one or more reference feature training vectors, the one or more reference feature training vectors representing one or more reference training features of at least one reference version of the at least one target training video; performing regression using at least one of the one or more target feature training vectors and at least one of the one or more reference feature training vectors to produce a video quality model; receiving a target video over the at least one communications channel; obtaining, from the target video, information pertaining to at least one or more target features of the target video; obtaining information pertaining to at least one or more reference features of a reference version of the target video; and obtaining a measurement of perceptual quality of the target video using at least the video quality model, the measurement of perceptual quality of the target video being based at least on the information pertaining to the one or more target features of the target video, and the information pertaining to the one or more reference features of the reference version of the target video.
