查询词典 speckle

Wavelet transform is introduced into the study of scene matching. The first application is to reduce speckle noise in SAR images and the other one is using wavelet_based multiresolution analysis in hierarchical matching. A new nonlinear wavelet transform-morphologic Harr wavelet transform, which suit for hardware realization is presented for matching application.
