Abstract :
A new speckle reduction approach, which estimates texture parameters simultaneously by the method of maximum likelihood under the assumption of multi-texture, is proposed. Comparison with the polarimetric whitening filter (PWF) shows that this approach preserves the polarimetric properties and reduces the couple between polarimetric channels.
