This is a pure Julia implementation for 1D, 2D, 3D and arbitrary-D phase unwrapping code based on:

Run Pkg.clone("https://github.com/platawiec/Unwrap.jl").
The interface consists of a single function, unwrap:
using Unwrap
unwrapped_array = unwrap(wrapped_array)where wrapped_array is an AbstractArray. There is also an
in-place version, unwrap!(A) which mutates A. The returned array will have
the same precision as A (i.e. BigFloat, Float32, etc. work). Type
?unwrap for more.
1D, 2D, and 3D unwrapping are all supported, as well as arbitrary dimensions, for whatever reason.
The package DSP.jl provides the one-dimensional version of unwrap! and unwrap. This package will live and be maintained in the JuliaDSP ecosystem.
Outside of the cited papers, interface and inspiration also taken from python's phase-unwrap: https://github.com/geggo/phase-unwrap
