Theseus
Warp
The
Theseus Warp technique assumes area sampling and resampling
in contrast to point sampling and resampling. Complete,
continuous, contiguous and uniformly weighted area resampling
delivers high fidelity image transformation with a lesser
computational cost than bi-cubic resampling.
| Area
Resampling |
| Complete
and Uniform:
Every
input pixel contributes a weight of exactly
1 to the output image.
Contiguous
and Continuous:
Contiguous
resampling apertures with continuously
varying size, shape and position over
the input image.

Incomplete
and Nonuniform:
Selected
input pixels contribute with varying weights
to the output image.
Non-Contiguous
and Discrete:
Non-contiguous
resampling apertures of constant size
and shape are positioned discretely over
the input image.
