MATLAB: Phase unwrapping in 2D

image analysisImage Processing ToolboxMATLABsignal processingSignal Processing Toolbox

I need to perform phase unwrapping in 2D using MATLAB, but the unwrap function seems to work only in 1D.
I want to have a routine similar to this one, available in a Python library:
http://scikit-image.org/docs/dev/auto_examples/filters/plot_phase_unwrap.html
Any suggestions?

Depending on what your data looks like, you may be able to simply use "unwrap" on the two different dimensions.
 A = unwrap(A,[],1);
 A = unwrap(A,[],2);
This is not generally true however, to unwrap data in two dimensions may need more advanced algorithms; unfortunately these are not built into MATLAB.
There are a number of user submitted functions on MATLAB central though which may help your further: https://in.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=phase+unwrap
Note that MathWorks does not offer support on MATLAB Central submissions. For help or comments on functions provided on MATLAB Central please contact the authors of the functions.
