errors, which are quantified as number of missing pixels.

Rendering a scene using a single depth image suffers from
disocclusion errors as the view translates away from the reference
view. We present the depth discontinuity occlusion camera
(DDOC), a non-pinhole camera that samples surfaces which are
hidden in the reference view, but are likely to become visible in
nearby views. The DDOC reference image alleviates disocclusion
errors; since it has a single layer, it maintains the advantages of
regular depth images such as bounded number of samples,
efficient incremental processing, and implicit connectivity. The
DDOC is defined by the reference view and the geometry it
encompasses. The reference planar pinhole camera is 3D distorted
at depth discontinuities. The distortion is fine-grain controlled
