Improvements
	Unconstrained camera viewpoints • Space carving [Kutulakos & Seitz 98] Evolving a surface • Level sets [Faugeras & Keriven 98] • More recent work by Pons et al. Global optimization • Graph cut approaches > [Kolmogoriv & Zabih, ECCV 2002] > [Vogiatzis et al., PAMI 2007] Modeling shiny (and other reflective) surfaces • e.g.,  Zickler et al., Helmholtz Stereopsis See today’s reading for an overview of the state of the art
