    Qian Kemao
    School of Computer Engineering, Nanyang Technological University, Singapore
    Appl Opt 46:7412-8. 2007
    ..The analysis shows that principles of the RPT, MPLS, WFR, and ACF are equivalent and the SCAF also leads to the WFR by some extension, which elegantly unifies all these methods for filtering unwrapped phase maps...

    Qian Kemao
    School of Computer Engineering, Nanyang Technological University, Singapore, 639798
    Appl Opt 49:1075-9. 2010
    ..The polynomial order of 4 is suggested for the CO-LSF, as higher order polynomials do not give significant improvement to the WFF-QG. One disadvantage of the CO-LSF is that it is more sensitive to phase discontinuities than the WFF-QG...

    Wenjing Gao
    School of Computer Engineering, Nanyang Technological University, Singapore
    Opt Express 17:23147-52. 2009
    ..Up to 132x speedup is obtained for WFT-based algorithms using NVIDIA GTX295 graphics card than sequential C in quad-core 2.5GHz Intel(R)Xeon(R) CPU E5420...

    Haixia Wang
    School of Computer Engineering, Nanyang Technological University, Singapore
    Opt Express 17:15118-27. 2009
    ..Demodulation results from one computer-simulated and two experimental fringe patterns using the proposed methods will be demonstrated...

    ..Theoretical analysis as well as simulation and experimental verifications are addressed...
  6. doi request reprint Statistical analysis for windowed Fourier ridge algorithm in fringe pattern analysis
    Wenjing Gao
    School of Computer Engineering, Nanyang Technological University, Singapore, 639798
    Appl Opt 51:328-37. 2012
    ..The above theoretical analysis and comparison are verified by Monte Carlo simulations. Furthermore, the WFR algorithm is shown to be slightly better than the WFF algorithm for quadratic phase...

    School of Computer Engineering, Nanyang Technological University, Singapore, 639798
    Appl Opt 50:1687-96. 2011
    ..Theoretical analysis shows that the four filters are largely equivalent to each other. Quantitative results are given on simulated fringe patterns to validate the theoretical analysis and to compare the performance of these filters...
