Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality. Digital Video Quality first introduces the concepts of human vision and visual quality. Based on these, specific video quality metrics are developed and their design is presented. These metrics are then evaluated and used in a number of applications, including image/video compression, transmission and watermarking.<uDigital videoImage processingDigital techniquesImaging systemsImage qualityElectronic books.Digital video.Image processingDigital techniques.Imaging systemsImage quality.006.6/96006.696621.38833Winkler Stefan965290MiAaPQMiAaPQMiAaPQBOOK9910143580603321Digital video quality2190178UNINA02143nam 2200373 n 450 99639635400331620221108023958.0(CKB)4330000000358552(EEBO)2240897043(UnM)99839323(EXLCZ)99433000000035855219901207d1578 uy |engurbn||||a|bb|A very comfortable, and necessary sermon in these our dayes, made by the right reuerend father, and faithful seruaunt of Iesus Christ Martin Luther, concernyng the commyng of our sauiour Christ to iudgement, and the signed that go before that last day.
