Sheng Wen-bin · Natural Science Journal of Xiangtan University · 2010
In this paper,a new edge-based synthetic aperture radar(SAR) image and satellite optical image matching algorithm has been put forward.In this algorithm,first a edge feature extraction method has been proposed for the inherent characteristics of SAR image,and a new sub-templates Hausdorff metric distance matrix method based on the edge continuity of density-weighted,using the Frobenius norm of sub-templates Hausdorff distance matrix to describe the scale of entire matrix size,establishing image similarity measurement.This measurement is reliable,robust,and has the advantages of easy parallel implementation.Test results show that this algorithm has good robustness,high matching precision,high calculation speed.
