Abstract

Due to its effectiveness in fringe pattern analysis, a fast implementation of windowed Fourier transform (WFT)-based algorithms is desired. In this work, we speed up the implementation in two aspects. First, we speed up the computation of Fourier transform, which is a core component of the WFT-based algorithms. Second, we parallelize the main body of these algorithms due to its parallel characteristic. With these two approaches, we obtain a 10× faster implementation than the original MATLAB version.
