Description
In this paper, we present a novel image-based
rendering technique, which we call manifold hopping. Our technique
provides users with perceptually continuous navigation by using only a
small number of strategically sampled manifold mosaics or multi-perspective
panoramas. Manifold hopping has two modes of navigation: moving continuously along
any manifold, and discretely between manifolds. An important feature of
manifold hopping is that significant data reduction can be achieved without
sacrificing output visual fidelity, by carefully adjusting the hopping
intervals. A novel view along the manifold is rendered by locally warping a
single manifold mosaic using a constant depth assumption, without the need for
accurate depth or feature correspondence. The rendering errors caused by
manifold hopping can be analyzed in the signed Hough ray space. Experiments
with real data demonstrate that we can navigate smoothly in a virtual
environment with as little as 88k data compressed from 11 concentric
mosaics.
