Description: Two- dimensional Wavelet Decomposition and Reconstruction Program Description
Main function
Mymain.m: by calling the function written by the two-dimensional wavelet decomposition and reconstruction of the signal
Main.m: using MATLAB wavelet transform function to achieve
2. Call the subfunction
Function [x2, cA, cV, cH, cD] mydwt2 (x, Lo_D, Hi_D)
The function mydwt () performs two-dimensional wavelet decomposition on x
The input parameters are x, Lo_D, Hi_D
X for the input signal, Lo_D for the low-pass filter, Hi_D for the high-pass filter
Output parameters: cA, cV, cH, cD- are the four sub-matrices of the wavelet decomposition coefficient matrix
X2 is the wavelet decomposition coefficient matrix
CA: low frequency partial decomposition factor cH: horizontal decomposition factor
CV: vertical direction decomposition coefficient cD: diagonal direction decomposition coefficient.
Function y myidwt2 (cA, cV, cH, cD, Lo_D, Hi_D)
The function myidwt2 ()
