Theoretical model and optimal prefilter for view interpolation
This paper discusses a view interpolation problem where a new view would be synthesized at the midst of two parallel views. We first introduce a new theoretical model that describes the relation between accuracy of disparities and the quality of the interpolated view. Then, we derive the optimal prefilter that minimizes the power of errors on the interpolated view. Our approach is inspired by the rate-distortion theory for video coding, and can be also regarded as an attempt to reconsider the plenoptic sampling theory. Finally, we present numerical simulations and experimental results to validate our theory.
