Hoping that your relatives remember some terms from when they were in school oh so many decades ago, you begin dropping all manner of 10$ words about orthogonal vector spaces, transforms, continuous wavelets, Discrete wavelets, fast wavelets, lifting schemes, wavelet packet decomposition, fractional Fourier transforms, you tried it all and were met by a blank stare from you father. You weren’t sure if they were trying to follow along of waiting for you to stop.
What do you do?
