Collaborative Filtering Technique for SAR Image Speckle Noise Suppression

Artur Gromek , Luigi Castaldo


Collaborative filtering is a technique used for image restoration among noise and distortions. Based on the fact that an image content has a locally sparse representation in transform domain. Technique employs a non-local modeling of image by collecting similar 2D image patches into 3D groups. The so-called collaborative filtering applied on such a 3D groups is realized by transform domain shrinkage and Wiener filtration. In this work, we implement collaborative filtering algorithm and test it on Synthetic Aperture Radar (SAR) imagery. The experimental results will be presented.
