I am working with fringe pattern projection. I designed a system that follow these steps: 1-)generating fringe pattern 2-)capturing the image 3-)taking FFT then bandpass at f0 and IFFT. 4-)unwrapping the phase in the unwrapping part, i used goldstein algrotihm which is avaible on mathworks. At the phase residues part, i cannot get any values on residues. All of my values in that part become zero. When i looked the example image on the codes, there are some 1 and -1 values at residues. Is there any alternative solutions for local phase unwrapping.

1 and -1 values represent residue whereas zero represent no residue.
