I need to construct a non-standard wavelet filter using the factorisation technique / Daubechies method / applied to the wavelet family / any /. I need to obtain the wavelet coefficients. The problem is I can't even find a tutorial on how to perform the factorisation method. I've read Ingird Daubechies Paper on factoring wavelet transforms into lifting steps / here /, read everything Paul Abbott and Mark Maslen wrote and still can't even figure out if I am on the right track. Everything is welcome: tutorials, guides, examples :) Thanks !
