| 2 | * AuthenTec AES3500/AES4000 common routines | ||
| 3 | * | ||
| 4 | * The AES3500 and AES4000 sensors are press-typed, and could capture | ||
| 5 | * fingerprint images in 128x128 and 96x96 pixels respectively. They | ||
| 6 | * share a same communication interface: a number of frames are | ||
| 7 | * transferred and captured, from which a final image could be | ||
| 8 | * assembled. Each frame has fixed height of 16 pixels. | ||
| 9 | * | ||
| 10 | * As the imaging area is a bit small, only a part of finger could be | ||
| 11 | * captured, the detected minutiae are not so many that the NBIS | ||
| 12 | * matching works not so good. The verification rate is very low at the | ||
| 13 | * moment. | ||
| 14 | * | ||
| 15 | * This work is derived from Daniel Drake's AES4000 driver. | ||
