Light Field Rendering for non-Lambertian Objects

In this paper we propose a solution for view synthesis of scenes presenting highly non-Lambertian objects. While Image- Based Rendering methods can easily render diffuse materials given only their depth, objects present non-linear displacements features, characterized by curved lines in epipolar plane images. Hence, to replace the depth maps used rendering new viewpoints more complex “non- Lambertian map” describing light field?s behavior. 4D field, features are linearly displaced following disparity, but feature follow any trajectory and need be approximated maps. We compute those from nine input images using Bezier or polynomial interpolation. After map computation, classical method is applied warp novel viewpoints.
