Perceptual preference for 3D interactions and realistic physical camera motions on light field displays

In this paper, we present our results on the empirical studies carried out on perceptual preference regarding the potential interaction techniques and the different types of realistic physical camera motions for light field visualization. The contents of the subjective tests were displayed on a large-scale light field cinema system. Multiple subjective quality metrics were used to decompose the visual experience of the observers, and additional attention was paid to the essential aspects of long-term usage, such as dizziness

Through a different lens : the perceived quality of light field visualization assessed by test participants with imperfect visual acuity and color blindness

With the emergence of commercially-available light field displays, both industry and academia have begun research on the potential use cases of future society. However, while there is an unfortunate global trend that the eyesight-related issues are getting more common among the new generations, such individuals are underrepresented in light field research. In this paper, we present the results of the series of subjective tests carried out on light field displays, exclusively with test participants that otherwise would not qualify to assess visualization quality in a regular study. The investigated topics include spatial resolution, angular resolution and viewing distance

Towards reconstructing HDR light fields by combining 2D and 3D CNN architectures

High dynamic range imaging has recently become a technological trend, with numerous attempts to reconstruct HDR images and videos from low-dynamic-range data. The reconstruction of light field images is analogous to the reconstruction of HDR videos, within which consecutive frames are temporally coherent. For light field images, many similarities exist between the adjacent views, since they visualize the same scene from different angular perspectives. In this paper, we investigate the theoretical possibilities of combining CNN architectures utilized for HDR images and videos in order to enhance the outputs of HDR light field image reconstruction
