Densely-sampled light field (DSLF) is a discrete representation of the 4D approximation of the plenoptic function, where multi-perspective camera views are arranged in such a way that the disparities between adjacent views are less than one pixel. DSLF is an attractive representation of scene visual content, particularly for applications which require ray interpolation and view synthesis. However, direct DSLF capture of real-world scenes is not practical. In this Grand Challenge, proponents are invited to develop and implement algorithms for DSLF reconstruction from decimated-parallax imagery, i.e. from a given sparse set of camera images.
