How fast did you swipe? Did you try fprint_demo to check > the quality of fingerprint? Usually I swipe somewhat fast (same speed as I would on my UPEK in my laptop). I don't have a mm per sec. speed, but I would imagine its regular swipe speed :) The quality in fprint_demo varies, and usually I can't get through a enroll phase. The first image looks good (although a bit more "rough" and interlaced compared to my UPEK, but then usually it stops with either just some black lines, or nothing, in a second image. It's almost like it detects my finger again, after I removed it.
Note that this reader is a cheap dealextreme unit (http://www.dx.com/p/mini-usb-2-0-biometric-fingerprint-reader-password-security-lock-for-pc-109073#.UzHzM9ud58M), that has a very "chinese" (without being offensive) feel to it, if you know what I mean. I am thinking if I should switch to a more robust and expensive alternative, but I guess thats another issue :) > > > > etes603:debug [process_remove_fp_end] Removing 498 empty lines from > > image > > etes603:debug [process_remove_fp_end] Removing 496 empty lines from > > image > > > Here the second fingerprint seems empty...
