Abstract :
Presents a classification overview and a comparative study of despeckling algorithms. Almost all of the existing good speckle reduction algorithms show high computational complexity. Promising results giving a very good compromise between image enhancement and algorithm complexity are obtained using multiscale analysis techniques
