title: C/C++ Wavelet library, non-GPL
body: <p>Ideally what I'd like to find is something with a simple, straightforward interface to multiple wavelet categories, like the GSL, but which has a license that lets me use it in proprietary software.  The <a href="https://stackoverflow.com/questions/9606458/looking-for-a-good-c-c-wavelet-library-for-signal-processing">top answer here</a> lists 10 Wavelet libraries, however all but one are licensed under the GPL, and <a href="http://www.maven.de/code/wavelet/index.html" rel="nofollow noreferrer">the one that isn't</a> seemed a little heavyweight, with the wavelet calculation wrapped up within larger image-processing functionality (which I'm not doing).  In any case I would like to have more options.  </p>
  
  <p>I also found <a href="http://www.cse.cuhk.edu.hk/~ttwong/demo/dwtgpu/" rel="nofollow noreferrer">this</a>, which looks cool, but it presumes a cuda-capable GPU and I can't assume that.</p>
