Despeckling of SAR images by directional representation and directional restoration

Despeckling algorithm for synthetic aperture radar (SAR) imagery, which uses directional representation and directional bases effectively to achieve comprehensive results. The directional representation directly relies on the multiplicative noise model and directional bases are used in coherent system model for restoration purpose. The proposed method is evaluated using qualitative analysis on real SAR data and quantitative analysis on simulated data. The results of the evaluation show that the proposed despeckling method outperforms the other despeckling algorithms.
