Paper Abstract

A new technique for efficient speckle reduction in synthetic aperture radar (SAR) images using wavelet packets is proposed. A phenomenological approach is used in adapting the wavelet packet transform to minimize the speckle coefficients. With thresholding and averaging, the resulting non-linear, multirate filtering can be used to preprocess images for reduction of speckle while retaining contrast in key objects necessary for target classification. An example of the algorithm using a SAR image is provided.
