UHD Video Dataset for Evaluation of Privacy

Ultra High Definition (UHD) is one of the emerging immersive video technologies already available to public, as even some of the smartphones are capable of capturing UHD video. The increasingly widespread availability of UHD capable recording devices has important implications on privacy. This paper addresses the problem by proposing a publicly available UHD video dataset designed for evaluation of privacy issues. The dataset depicts typical surveillance scenarios of people fighting, exchanging bags, walking, and stealing, in an indoor and outdoor environment. The dataset also includes the data from the subjective assessment, which evaluated the impact of UHD on privacy compared to a currently common High Definition (HD) video and declining Standard Definition (SD) video. The results of the assessment not only demonstrate that UHD is a significantly more privacy intrusive technology when compared to HD and SD used today, but they also quantify the impact of intrusiveness.
