* AuthenTec AES3500/AES4000 common routines
|
|
*
|
|
* The AES3500 and AES4000 sensors are press-typed, and could capture
|
|
* fingerprint images in 128x128 and 96x96 pixels respectively. They
|
|
* share a same communication interface: a number of frames are
|
|
* transferred and captured, from which a final image could be
|
|
* assembled. Each frame has fixed height of 16 pixels.
|
|
*
|
|
* As the imaging area is a bit small, only a part of finger could be
|
|
* captured, the detected minutiae are not so many that the NBIS
|
|
* matching works not so good. The verification rate is very low at the
|
|
* moment.
|
|
*
|
|
* This work is derived from Daniel Drake's AES4000 driver.
