To interpolate or not to interpolate: Subjective assessment of interpolation performance on a light field display

Interpolating virtual views from sparse visual content increases the angular resolution of the visualization. However, such techniques may degrade the image quality through inaccurate view estimation. The smooth motion parallax through increased angular resolution, and image quality are essential components of the overall user experience. The choice of interpolation initiates an unclear trade-off between them. In this paper, we introduce our research on interpolation techniques for 3D light field visualization. We examined the performance and perceived quality of selected algorithms, in a series of subjective quality assessment experiments. Our results show an obvious interpolation technique preference on visual contents with low angular resolutions.
