A New Method for Multi-Spectral and SARRemote Sensing Image Registration
Considering the shortcomings of low accuracies in manual selecting registration control points (RCP) and difficulties in extrcting regions and edges because of SAR speckle noise in the registration for multi-spectrum and SAR remote sensing images
a new registration method for multi-spectrum and SAR images is presented in this paper. With the images of Landsat TM and JERS-1 SAR
this method extracts the RCP from the correlation of the binary classified images
and the RCP accuracies are improved with surface spline interpolation. Because the texture characters of SAR speckle noise are employed in SAR image classification
the speckel noise is no longer obstacles in the registration
and all these efforts make the registration errors of experiment images lower than a pixel.
