Embodiment Construction
[0046] Those skilled in the art can realize the purpose of the present invention through the above description of the content of the present invention and the further description of the following implementation examples. However, this embodiment is only a part of the present invention and should not be taken as limiting the scope of the present invention.
[0047] Contourlet transform is a multi-resolution, flexible locality and directional information representation method realized by using Laplacian Pyramid (LP) and Directional Filter Bank (DFB). The Laplacian pyramid decomposition realizes the multi-resolution analysis of the signal, and the LP decomposition of each level produces a downsampled low-pass part and a non-downsampled high-pass part, as shown in Figure 4, H 0 ,H 0 Respectively, the decomposition and synthesis filters in the decomposition process, H 1 ,G 1 are the decomposition and synthesis filters in the reconstruction process, respectively, and M is the sam...
