Information extraction form single look complex SAR images

This paper proposes despeckling using the regularization framework. In order to separate the scene and speckle an auto-binomial model is used. The cost function consists of an auto-binomial prior, system response function and the differential part. The minimization problem is solved using a quasi-Newton approach. The system function term estimates the amount of speckle, the prior estimates the properties of the scene, the differential is used to preserve the point like characteristics of SAR image.
