Quality assessment of color reproduction devices: Cross-media vs. single- media

摘要

Nowadays, the visual information is widely used for several applications such as medical diagnosis, video-surveillance... This information needs to be displayed in order to exploit the contained data. So, the display devices market is growing very quickly and the used technologies are different from a manufacturer to another. This leads to a need of a comparison between displays of different technologies but also ones from the same technology. In this paper, we describe two methodologies that we have used, for a subjective cross-media evaluation and a single media evaluation, in the context of image quality for display reproduction. We compare the results obtained by the two methodologies in order to determine if it is possible to replace a cross-media evaluation by a single media evaluation. We describe how we have used, the characterization of a display in order to simulate a display color reproduction on another one. We explain the different statistical non-parametric tests that we have used, to analyze the results. And we discuss about the results obtained for the two cases, and the possibility to replace a cross-media evaluation by a single-media evaluation.
