Effect of Primitive Features of Content on Perceived Quality of Light Field Visualization

Due to recent advent of light field visualization, acquisition/creation, encoding, transmission, rendering and quality assessment of 3D light field content has gained momentum. In particular, large light field displays need content with large field of view, and with high spatial and angular quality. Accordingly, subjective and objective quality evaluation studies have been conducted to examine spatial, angular and spatio-angular aspects of light field visualization. Recently, the effect of various zooming levels of the displayed content, as well as regions of interest on Quality of Experience (QoE) has also been explored. However, there has been no systematic attempt to see how the features of the content itself affect the visualization quality. In this work, we attempt to examine the effects of some primitive features of the content on subjective QoE. The results are based on a subjective study conducted on a large light field display, offering virtually continuous horizontal parallax.
