#include <RWaveletDenoisingOp.hpp>
Inheritance diagram for RWaveletDenoisingOp:
Purpose: Wavelet denoising via shrinkage of wavelet coefficient with soft threshold.
Wavelet type used is QMF.
Source: This is a C++ implementation of original code of Hilton for comparision and integration
purposes. The original c sources are provided in the originGnuCode directory(included).
