Definition
Image and video quality assessment deals with quantifying the quality of an image or video signal as seen by a human observer using an objective measure.
Introduction
In this article, we discuss methods to evaluate the quality of digital images and videos, where the final image is intended to be viewed by the human eye. The quality of an image that is meant for human consumption can be evaluated by showing it to a human observer and asking the subject to judge its quality on a pre-defined scale. This is known as subjective assessment and is currently the most common way to assess image and video quality. Clearly, this is also the most reliable method as we are interested in evaluating quality as seen by the human eye. However, to account for human variability in assessing quality and to have some statistical confidence in the score assigned by the subject, several subjects are required to view the same image. The...
