| Summary: | 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
spatial domain and the 1D windowed Fourier transform in the temporal domain are two special cases of the
proposed method. The principles of windowed Fourier filtering and windowed Fourier ridges are developed.
Experimental verification shows encouraging results despite a longer processing time. |
