Abstract:
Image denoising and enhancement plays an
important role in the field of Synthetic Aperture
Radar (SAR) imagery. The geographical features
detection applications such as road detection are
very demanding. The objective of image
enhancement is to improve the visibility of lowcontrast
features while suppressing the speckle. It
improves the visible quality of the image. Image has
locally varying statistics, has different edges and
smoothness in it. Speckle reduction can be done on
an image by wavelet analysis. Wavelet gives a
superior performance in speckle reduction due to
properties such as sparsity and multi resolution.
