Right.
I was refering to a method closer to "optimal adaptive quantization" like
Dirk Farin is doing research on:
http://citeseer.nj.nec.com/farin02ratedistortion.html
I wanted to test if this can be combined with the paper
$\rho$-domain estimated and make the whole thing a little
less "optimal", because otherwise it would get too slow.
