Multi-Resolution Fourier Analysis Part I: Fundamentals
In the first paper of this series, we propose a multi-resolution theory of Fourier spectral estimates of finite duration signals. It is shown that multi-resolution capability, achieved without further observation, is obtained by constructing multi-resolution signals from the only observed finite duration signal. Achieved resolutions meet bounds of the uncertainty principle (Heisenberg inequalit...
متن کاملWindowed Fourier transform for fringe pattern analysis: addendum.
Novel approaches based on windowed Fourier transform for demodulation of fringe patterns were previously presented [Appl. Opt. 43, 2695-2702 (2004)], where extraction of phase and phase derivatives from either phase-shifted fringe patterns or a single-carrier fringe pattern was the main focus. I show that the same methods can be applied to process a single closed-fringe pattern in either noise ...
متن کاملPhase Imaging: Unwrapping and Denoising with Diversity and Multi-resolution
Many imaging techniques, e.g., interferometric synthetic aperture radar (InSAR), and magnetic resonance imaging (MRI), yield phase images. In these, generally, each pixel retrieves the phase up to a modulo-2π rad ambiguity, i.e., the phase wrapped around the principal interval [−π π[. Phase unwrapping (PU) is, then, a crucial operation to obtain absolute phase, which is where physical informati...
متن کاملGeneralized 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 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 Four...
متن کاملInterferometric Multi-chromatic Analysis of High Resolution X-band Data
The Multi-Chromatic Analysis (MCA) consists of performing sub-bands splitting in range frequency domain, thus generating chromatic views of lower range resolution, centered at different carrier frequencies. Multi-chromatic interferograms can be then generated by coupling chromatic views coming from an interferometric pair of SAR images. The interferometric phase of spectrally-stable scatterers ...
