Discrete Multiwavelet Transform Based SAR Image Speckle Reduction.
Sujit Bhattacharya, V. R. Gujaraty, Shailendra S Rana · 2002
Speckle noise usually occurs in Synthetic Aperture Radar (SAR) images owing to coherent processing of SAR data. This paper proposes and investigates the Speckle reduction and enhancement of SAR images with multiple wavelets (Multiwavelets). Multiwavelets transformations are useful for speckle reduction through its sub-band images and the speckle reduction is obtained by thresholding the subband images coefficients of the digitized SAR images. generalized Cross...
