Abstract:
We present wavelet warping - a new class of forward 3D warping
algorithms for image-based rendering. In wavelet warping most of the warping
operation is performed in the wavelet domain, by operating on the coefficients
of the wavelet transforms of the images and other matrices defined by the mapping.
Operating in this fashion is often more efficient than performing the 3D
warp in the standard manner. Perhaps more importantly, operating in the wavelet
domain allows one to perform the 3D warping operation progressively and to generate
target views at multiple resolutions. We describe wavelet warping of planar,
cylindrical, and spherical reference images and demonstrate that the resulting algorithms
compare favorably to their standard counterparts. We also discuss and
demonstrate utilization of temporal coherence when wavelet-warping image sequences.
