| Abstract: | Some new time frequency filtering methods such as threshold, cycle spinning filtering algorithms based on Contourlet transform were studied. After compared and analyzed with the filtering methods based on DWT (Discrete Wavelet Transform) and the Golstein in the number of residues and the coherence value it can be seen that the new algorithms keep the details of interferogram very well, reduce more residues, and the filtering effect is much better than the classical soft threshold method based on DWT, and even as good as Goldstein in a certain condition. |
