1. A system for automatically morphing four-dimensional (4D) light fields, comprising: providing a source light field representing a first 3D object; providing a target light field representing a second 3D object; specifying corresponding feature elements in at least one view of both the source and target light fields; warping the source and target light fields to align the feature elements; and blending the warped light fields to produce a composite light field representing a morphed light field.
