Fast 2D phase unwrapping
Fast unwrapping 2D phase image using the algorithm given in:
M. A. Herraez, D. R. Burton, M. J. Lalor, and M. A. Gdeisat, "Fast two-dimensional phase-unwrapping algorithm based on sorting by reliability following a noncontinuous path", Applied Optics, Vol. 41, Issue 35, pp. 7437-7444 (2002).
Features and advantages:
* Fast algorithm (takes approx. 0.5s to unwrap 512x512 non-noisy and noisy image in my computer)
* Support ignored regions, by setting NaN to the ignored regions.

Version | Published | Release Notes | |
---|---|---|---|
1.1.0.0 | Further optimizing the performance by: * reducing cell operations, and
The result is it is now around 2x as fast for no-noise case, and much faster in noisy case (more than 5x faster). |
