InverseTransform


Unit:SDL_wavelet
Class:TWavelet1D
Declaration:procedure InverseTransform (Level: integer);

The method InverseTransform performs a multi-level one-dimensonal wavelet synthesis using the wavelets specified by the property WaveletFamily. The parameter Level defines the level to which the synthesis is performed. It may take values between 1 and log2(Size). The synthesis is an in-place synthesis reading the wavelet coefficients from the Data buffer and writing the resulting signal back into this buffer.

The process of the synthesis is shown in the following figure (a 3-level synthesis in this example):

Example: This method is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): waveletfilter, waveletcoeff
