thanks for this
if you have some free time can you explain how it activity work?
i look doc.. and understood nothing else than formula
i read code and found a  different formula
so i cna't undestodd very well what it has done=)

this is what i can understood.
 activity  = edge detection using diffrence between adiacent pixel
then it work on this activity  making  average activiti and something else i 
cant' understood..
then it use an expression to comute the value of quantizer 
am i right?
