Generalized three-dimensional windowed fourier transform for fringe analysis

Generalized three-dimensional windowed fourier transform for fringe analysis

A 3D windowed Fourier transform is proposed for fringe sequence analysis, which processes the joint spatial and temporal information of the fringe sequence simultaneously. The 2D windowed Fourier transform in the...
