Multilevel 2-D wavelet reconstruction



waverec2 is a two-dimensional wavelet analysis function.

X = waverec2(C,S,'wname') performs a multilevel wavelet reconstruction of the matrix X based on the wavelet decomposition structure [C,S] (for detailed storage information, see wavedec2). 'wname' is a string containing the name of the wavelet (see wfilters for more information).

Instead of giving the wavelet name, you can give the filters. For X = waverec2(C,S,Lo_R,Hi_R), Lo_R is the reconstruction low-pass filter and Hi_R is the reconstruction high-pass filter.

waverec2 is the inverse function of wavedec2 in the sense that the abstract statement waverec2(wavedec2(X,N,'wname'),'wname') would give back X.


Note that X = waverec2(C,S,'wname') is equivalent to X = appcoef2(C,S,'wname',0).
