Let say i have a image that I defined using img = pasted
pictured. Then I do a wavelet transfom:
dwd = DiscreteWaveletTransform[img,DaubechiesWavelet,3]. Now I can use
WaveletImagePlot[dwd] to look at the wavelet levels. I would like to do an
histogram on all or some level of dwd. I can't find how to do it. I looked
at WaveletMapIndexed, but I cant figure out how to do it....
Any help will be appreciated.
