Query: A Study on Visual Perception of Light Field Content   The effective design of visual computing systems depends heavily on the
anticipation of visual attention, or saliency. While visual attention is well
investigated for conventional 2D images and video, it is nevertheless a very
active research area for emerging immersive media. In particular, visual
attention of light fields (light rays of a scene captured by a grid of cameras
or micro lenses) has only recently become a focus of research. As they may be
rendered and consumed in various ways, a primary challenge that arises is the
definition of what visual perception of light field content should be. In this
work, we present a visual attention study on light field content. We conducted
perception experiments displaying them to users in various ways and collected
corresponding visual attention data. Our analysis highlights characteristics of
user behaviour in light field imaging applications. The light field data set
and attention data are provided with this paper.
