%MATLAB 5.x code for implementing the zpim algoritm % (see IEEEIP, vol 11, no. 4, pp. 408-422, 2002) % %========================================================================= %-- The zpim absolute phase estimation algorithm % % The zpim algoritm computes the absolute phase difference from % an interferogram or from a pair of SAR/SAS images (InSAR/InSAS pair). % The alhorithm is iterative and implements an unwrapping step % (Z-step) and a smoothing step (pi-step) on each iteration. % %======================================================================== %-- Z-step (Phase Unwrapping) % % The (Z-step) is a phase unwrapping algorithm and was coded in C and % compliled as MATLAB MEX file (zs.dll in the windows OS). % This code is based on the implementation of the Flynn minimum % discontinuity algorithm (see JOSA, vol. 14, no. 10, % pp. 201-208, 1997) by Ghiglia and Pritt (see D. Ghiglia and M. Pritt, % Two-Dimensional Phase Unwrapping. Theory, algorithms, and Software, % Wiley Inter-Science, 19***). In short, we have modified Flynn algorithm % to deal with non-integer differences and to minimize the l_2 norm of the % firt order phase diferences. See our paper for the details. % % See zm.m for a detailed explanation on how calling the MEX function zs(). % See also the functions zstep(), zstepd(), zstepq(), which wrapps % the MEX file zs(). % %======================================================================== %-- pi-step (Phase Smoothing) % % The pi-step applies smoothing to the output of the Z-step. % See function pistep(). % % See pistep.m for a detailed explanation. % %======================================================================== %-- zpim Algorithm % % The function zpim() codes the compete zpim algorithm. Type help zpim % for details. % %======================================================================== %-- Demos % % To get an understanding on how the complete package works, we have % provided the follwoinh demos: % % Illustrating the Z-step (Phase Unwarapping) % demoz1, demoz2, demoz3, demoz4, demoz5 % % Illustrating the pi-step (Phase Smoothing) % demozp1, demozp2, demozp3 % %Author: Jose M Bioucas Dias, June, 2003
