Digital Video Quality

Vision Models and Metrics

€ 150.95

Visual quality assessment is an interdisciplinary topic that links image/video processing, psychology, and physiology. Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality.
