VQuad-HD

It is a full-reference model, meaning that it requires access to the original and the degraded signal to estimate the quality.

It was the best performing model in the HDTV competition to find the new standard that was organized by the independent and non-commercial Video Quality Expert Group (VQEG).

The ITU-T J.341 Recommendation provides a perceptual video quality measurement method for use in High-definition television (HDTV) non-interactive applications when the full reference (FR) measurement method can be used.

The estimation process is based on the following steps: The objective model is tested on a wide variety of different frame-rates as used in TV applications (29.97 fps and 25 fps), in Interlaced video and Progressive scan mode at the resolution 1920⨉1080.

Content of 1280⨉720 was included in testing by up-sampling it to 1920⨉1080, as this is the typical case for most consumer applications.
