Multisensor Image Registration Using Modified Hausdorff Distance Matrix Metrics

As to multi-sensor image registration, a novel algorithm for registration synthetic aperture radar (SAR) image to Optical image based on Weight Hausdorff Distance Matrix (WHDM) Metric is proposed in the paper. In the proposed method, edge feature is used for common feature, which can solve the key problem brought by different senor. WHDM is designed as a similarity measure. Experimental results using synthetic and real images demonstrate that the proposed WHDM metric outperforms most existed Hausdorff Distance based (HD-based) methods, especially in higher level noise and that the proposed algorithm is robust, and can achieve high registration accuracy.
