Existing scene flow approaches mainly focus on twoframe stereo-pair configurations and reconstruct an imagebased representation of scene flow. Instead, we propose a variational formulation of scene flow relative to a coarse proxy geometry, which is better suited for many views. Furthermore, a linear basis is used to represent temporal surface flow, allowing for longer-range temporal correspondence with fewer variables. Our formulation takes known proxy motion into account (e.g, if the proxy is

Additionally, through the appropriate proxy and basis, our framework generalizes existing approaches for scene flow, optic-flow, and twoframe stereo. We illustrate results on real-data for both static and moving proxy surfaces over several frames.
