Abstract: 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 with a distortion map, which allows handling complex scenes. The DDOC provides fast projection so the reference image is constructed efficiently with the feed-forward graphics pipeline.
