Comparison of Fourier transform, windowed Fourier transform, and wavelet transform methods for phase calculation at discontinuities in fringe projection profilometry

► FT, WFT, and WT profilometry are compared on phase calculation at discontinuities. ► Simulated and experimental data are testified at edges by FT, WFT and WT methods. ► WFT profilometry has the best performance of measuring objects having discontinuities.
