| Abstract: | An adaptive speckle filtering algorithm is proposed.It detects image points belonging to edge based on wavelet transform.Speckle are filtered according to detect results and multi-look.Feasibility of this method is proved theoretically.Ex periment results demonstrate that edges are reserved and uniform areas are smoothed simultaneously un-der the proposed algorithm. |
