    Free-viewpoint thumbnail for light field compression



    This paper proposes a new JPEG-compatible coder of light field data. When viewing a 3D scene using light field data, we usually require a specialized light field viewer. However, the proposed coder produces an output file from which we can see a thumbnail of the light field by using common JPEG viewers. This thumbnail can be a free viewpoint image of the scene which reflects user’s preference or creator’s idea. We can also achieve good compression efficiency by using this thumbnail as a reference image.
