Surface light field is a light field parameterized to the surface of a geometric model. Although this multiview object representation enables rendering of objects from arbitrary views, the data size of a surface light field is huge. In this paper, a compression scheme is proposed. Together with compression efficiency, scalability and fast, memory efficient rendering is considered. To enable such functionalities, we base our compression scheme on a factorized representation of surface light field, and utilize a parameterization of the geometric model to a base mesh for application of wavelet transforms for progressive compression and scalable rendering. Experiments were conducted on a real world and synthetic data to study the compression efficiency and the characteristics of our proposed scheme.
