Speckle Reduction in Matrix-Log Domain for Synthetic Aperture Radar Imaging

Autor: Charles-Alban Deledalle, Loïc Denis, Florence Tupin

Publikováno v: Journal of Mathematical Imaging and Vision. 64:298-320

Synthetic aperture radar (SAR) images are widely used for Earth observation to complement optical imaging. By combining information on the polarization and the phase shift of the radar echos, SAR images offer high sensitivity to the geometry and mate

Blind atmospheric turbulence deconvolution

Autor: Charles-Alban Deledalle, Jérôme Gilles

Publikováno v: IET Image Processing. 14:3422-3432

A new blind image deconvolution technique is developed for atmospheric turbulence deblurring to overcome limitations of ‘generic’ blind deconvolution algorithms that do not take into account the complicated physics of the turbulence. The original

The availability of multi-temporal stacks of SAR images opens the way to new speckle reduction methods. Beyond mere spatial filtering, the time series can be used to improve the signal-to-noise ratio of structures that persist for several dates. Amon

International audience; In inverse problems, the use of an l(12) analysis regularizer induces a bias in the estimated solution. We propose a general refitting framework for removing this artifact while keeping information of interest contained in the
