How do I use Discrete Wavelet Transform for feature extraction on MRI images and export numerical data to Excel?

I have seen some research articles in which discrete wavelet transform is used for feature extraction on medical images. I would be very glad if I could be shown how this could be done in Mathematica 11. Secondly, I would like to export the numerical data after extraction to Excel so that I can compare them with static plots obtained from 3D slicer. Thanks guys!
