Image Processing Techniques and Applications

We present results of large-scale experimentation with the enhanced model-based despeckling (EMBD) filter aiming at its validation from a pragmatical point of view. Furthermore, we point out criteria for the choice of a prior model for synthetic aperture radar (SAR) images. These criteria rely on an evidence maximization step -part of the EMBD algorithm itself- and on the verification of the obtained speckle statistics against the assumptions made in the filtering.
