Coherence methods in mapping AVO anomalies and predicting P-wave and S-wave impedances [PDF]
, 2005 Filters for migrated offset substacks are designed by partial coherence analysis to predict ‘normal’ amplitude variation with offset (AVO) in an anomaly free area.

Partially coherent imaging and spatial coherence wavelets [PDF]
Optics Communications, 2004 A description of spatially partially coherent imaging based on the propagation of second-order spatial coherence wavelets and marginal power spectra (Wigner distribution functions) is presented. In this dynamics, the spatial coherence wavelets will be affected by the system through its elementary transfer function. The consistency of the model with the

Low-Coherence Interferometric Imaging: Solution of the One-Dimensional Inverse Scattering Problem [PDF]
, 2004 Optical coherence tomography (OCT) is a non-invasive imaging technique based on the use of light sources exhibiting a low degree of coherence. Low coherence interferometric microscopes have been successful in producing internal images of thin pieces of ...

Wavelet transform-based interferometric SAR coherence estimator [PDF]
IEEE Signal Processing Letters, 2005 A novel method to estimate interferometric coherence in synthetic aperture radar interferometry is proposed. It is demonstrated that this approach is not affected by the terrain topography, contrary to multilook techniques. In addition, since the method is based on the two-dimensional discrete wavelet packet transform, it allows recovering coherence ...
