Hi the problem with device-independent representation is that different sensors use different technology (touch sensors opposed to sweep sensors), and have different image size. if all these parameters are the same then the data could be theoretically device independent (note that libfprint stores driver-id in its files, so you would have to override this)
NBIS software (used internally by libfprint) can extract fingerprint data from an image, but AFAIK does not provide any functionality not used in libfprint Pavel On Friday 21 of November 2008 17:58:08 Zé Carlos wrote: > The blob type issue is not a problem for me, but the hardware-specific > generated code can be a problem, i need a hardware-independent > representation, i can't guarantee that all readers will have the same > brand.
