ADAPTIVE REGULARIZATION VARIATION METHOD FOR SAR IMAGE FEATURE-ENHANCEMENT AND SPECKLE-REMOVAL
Zheng Wang · JOURNAL OF INFRARED AND MILLIMETER WAVES · 2007
The problem of speckle removal and feature enhancement of SAR image was studied.Traditional speckle removal methods generally result in the lost of image features.Based on the idea of SAR image processing and the prior knowledge of SAR image,we presented an adaptive regularization variation method by constructing diffusion coefficient and regularization parameter.Theoretical analysis and numerical results demonstrate that the proposed method can efficiently depress the speckle and enhance the feature of SAR image.
