Thanks Daniel I undestand... but... :) the data that libs store of the image have some kind of representation... right? or the lib allways compare image <-> image?
meaby if i can get some "data" about the finguerprint... like an array of curves descriptors and points... this match can be done faster? i think i need to make a lot of research in order to find something.... 1st... i will read about how does the finguerprints are detected and what does the lib step by step to make a match... can you (or someone) sendme some links to this kind of docs??? Thanks in advance!!!
