Here we demonstrate the validity of our techniques on a scene with
complex BRDFs, textures and geometry. This scene consists of objects
with highly specular (metal) and anisotropic (velvet) BRDFs. There are
objects with complex textures as well as objects with no texture.
In addition, the metal ball has a complex shape with a significant
amount of occlusions and the fur teddy-bear has fine geometric structure.
There is global illumination in the fur and reflections from the shiny
table-top. Click on images for high-resolution versions.

Depth Recovery

Depth Map using multiple focal planes (Section 5.1).
Our techniques are robust to complex BRDF's, (lack of) textures and complex
geometries. Correct depth maps are computed even in the presence of severe
occlusions and depth discontinuities (metal ball).

Depth Map using two focal planes (Section 5.2).

Depth Map using single focal plane [23].
Incorrect depth-map due to reflections from the shiny table-top.
Notice the abrupt transition near the base of the red-cylinder and
the base of the sea-shells. In contrast, notice the correct smooth
transition in the depth maps computed using our techniques.
