摘要：
Wavelet footprints, recently proposed by Dragotti, are used for speckle reduction of Synthetic Aperture Radar (SAR) images. Wavelet footprints contain all wavelet coefficients associated with a singular structure of a signal. Consequently, the dependency across scales that is inherent in wavelet transformation is eliminated. In the present paper, coefficients of wavelet footprints are thresholded with hard thresholding. The denoising method shows great promise for speckle removal and hence provides good detection performance for SAR based recognition.
