Assessing Task-Based Video Quality — A Journey from Subjective Psycho-Physical Experiments to Objective Quality Models
This paper reviews the development of techniques for assessing video quality. Examples have been provided on the quality of video applications ranging from popular entertainment to new trends such as applications in broad public systems, not just those used by police forces but also for medical purposes. In particular, the author introduces two typical usages of task-based video: surveillance video for accurate licence plate recognition, and medical video for credible diagnosis prior to bronchoscopic surgery. The author also presents the field of task-based video quality assessment from subjective psycho-physical experiments to objective quality models. Example test results and models are provided alongside the descriptions.
