Finger almost never match
I'm using ubuntu 20.04 laptop and bought a external fingerprint reader identified as ELAN:Fingerprint ID 04f3:0c3d
。It's in the support list. I build and install the 1.94.2 version libfprint. fprintd-enroll
works fine, but fprintd-verify
almost results in 'verify-no-match'. I use enroll
and verify
in builddir/examples
for test, they generate enrolled.pgm and verify.pgm. I checks the 2 image , I think they are flip 180 degrees。Is that right?
verify.pgm
enrolled.pgm
Thanks for any help!
