Vasily Khoruzhick	e32fa8cc38	aes2501: Improve image contrast When scanning, check the histogram sum, and increase the ADREFHI register value if the sum is too low, or decrease it if it's too high. https://bugs.freedesktop.org/show_bug.cgi?id=56715	2012-11-05 19:49:54 +01:00
Daniel Drake	2ad14c0212	Add AES2501 driver This driver works quite nicely. Seems a little too sensitive though (too much black in the standardized image, not enough ridge gap definition). Processing results are quite good, but you need a good enrollment image (i.e. long!). It's best to get such images by pressing harder than you might think necessary and swiping slowly.	2007-11-15 09:54:39 +00:00

aes2501: Improve image contrast

When scanning, check the histogram sum, and increase the
ADREFHI register value if the sum is too low, or decrease
it if it's too high.

This driver works quite nicely. Seems a little too sensitive though (too
much black in the standardized image, not enough ridge gap definition).

Processing results are quite good, but you need a good enrollment image
(i.e. long!). It's best to get such images by pressing harder than you
might think necessary and swiping slowly.
