To perform this function, I have need of the function FwdInitAlloc, my question is how the filter must be allowed, for example with a Daubechies wavelet with an order is equal to 15.<BR />thanks.<BR /><BR />If you have one or several examples of this function, I'm interesting.<BR /> Tue, 19 Jun 2007 19:57:47 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Wavelet-transform/m-p/853622#M6838 j_bossu 2007-06-19T19:57:47Z https://community.intel.com/t5/Intel-Integrated-Performance/Wavelet-transform/m-p/853623#M6839 <P>Hi,<BR />it seems the easy way to start from 2D wavelet C++ project, which you may obtain in IPP samples package.
