Performance Analysis of SIFT Feature Extraction Algorithm in Application to Registration of SAR Image

Exactly extracting the stable feature of high resolution SAR image as well as matching it are two critical steps for the Antomatic regiestation systems. It is suggested that the Scale Invariant Feature Transform (SIFT) algorithm can be applied in the optical image registration systems and four representative experiments were performed to test its validity. It is found that SIFT can accurately register the high resolution SAR images than the traditional Harris in applicability and precision.
