A SAR Speckle Adaptive Filtering Algorithm in Spatial Domain
Chen Yingying · Journal of Tongji University · 2010
To suppress the speckle in Synthetic Aperture Radar (SAR) images,a novel adaptive algorithm based on SVR is proposed.A SAR image is regarded as a 2-D continuous function and is approximated by support vector regression(SVR).The regression result is used to describe the relationship among pixels.Based on the relationship,the noise is classified and suppressed.In the procedure of regression,the wavelet kernel function is used to improve the accuracy.The experiment results show that this method is effective.
