Abstract
Techniques are provided for perception enhancement of light fields (LFs) for use in integral display applications. A methodology implementing the techniques according to an embodiment includes receiving one or more LF views and a disparity map associated with each LF view. The method also includes quantizing the disparity map into planes, where each plane is associated with a selected range of depth values. The method further includes slicing the LF view into layers, where each layer comprises pixels of the LF view associated with one of the planes. The method further includes shifting each of the layers in a lateral direction by an offset distance. The offset distance is based on a viewing angle associated with the LF view and further based on the depth values of the associated plane. The method also includes merging the shifted layers to generate a synthesized LF view with increased parallax.
