+This test code will run a WaveletImageFilter on given input image. Output 
+from this filter is then fed to WaveletInverseImageFilter which does 
+the inverse transform. Hence output of inverse transform passed to
+ImageFileWriter will result in the input image. 
 
 Wavelet operator used is HAAR (otb::Wavelet::HAAR).
 This filter works only in single-threaded setup
