Abstract
We propose a new depth-based representation of 3-D scenes
primarily for the problem of arbitrary view synthesis. The information
contained in a given image sequence is compacted into a single
multivalued array, where points are organized by occlusions rather than
by coherent affine motions. This grouping facilitates an automatic
process to determine the number of layers and helps to reduce the
artifacts caused by occlusions in the scene. In addition, an iterative
multiframe dynamic programming algorithm is described to produce
piecewise smooth depth maps. A novel multiframe segmentation, tracking,
and plane fitting algorithm is also proposed to handle the traditionally
difficult low-contrast regions. Reconstructed views as well as arbitrary
flyarounds of real scenes are presented to demonstrate the effectiveness
of the approach
