>Z< Nonlinear Wavelet Processing for Enhancement of Images J.E. Odegard, M. Lang, H. Guo, R.A. Gopinath, C.S. Burrus

In this note we apply some recent results on nonlinear wavelet analysis to image processing. In particular we illustrate how the (soft) thresholding algorithm due to Donoho can successfully be used to remove speckle in SAR imagery. Furthermore, we also show that transform coding artifacts, such as blocking in the JPEG algorithm, can be removed to achieve a perceptually improved image by postprocessing the decompressed image.
