f = ifwt2(c,w,J) f = ifwt2(c,w,J,Ls,...)
| c | Coefficients stored in a matrix. |
| w | Wavelet filters definition. |
| J | Number of filterbank iterations. |
| Ls | Size of the reconstructed signal. |
| f | Reconstructed data. |
f = ifwt2(c,w,J) reconstructs signal f from the wavelet coefficients c using a J-iteration synthesis filterbank build from the basic synthesis filterbank defined by w. f is a matrix with size(f)==size(c).
f = ifwt2(c,w,J,Ls) works as above but the result f is cut or extended to size Ls if Ls is a two-element vector or to [Ls,Ls] if Ls is a scalar.
This function takes the same optional parameters as fwt2. Please see the help on fwt2 for a description of the parameters.
