Evaluation of Adaptive Filtering Techniques for Cleaning SAR, Laser Beamed Fringes and Ultrasonic Images from the Speckle Noise
Maria del Carmen VAIDES, Minoru Inamura · Journal of Agricultural Meteorology · 2005
We evaluate the results of the application of several filters already known, modified by means of adding adaptive mechanisms based on the statistical properties of the noise. We also demonstrate that some adaptive and/or recursive filters designed for reducing the speckle noise can be improved with a two-stages filtering process. The conventional filters that have served as basis for our study are tabulated and the results are evaluated.
