libdpfp 0.2.1 – basic image enhancement
I have just released version 0.2.1 of libdpfp, a userspace library with example programs to interact with Microsoft and DigitalPersona fingerprint scanners on Linux.
This release contains code from eFinger and FVS to enhance the fingerprint images. The capture_finger_enhanced example program now produces images like the ones in this post, which is rather cool. Again, the enhancement takes a few seconds to complete, hopefully we can improve on this. Also, I think I saw an infinite loop in the thinning code, but have been unable to reproduce this.
Andrei Tchijov has done some work porting libdpfp to Mac OS X (Darwin). I say porting, only a few small changes were needed. It doesn’t work out-of-the-box on Darwin just yet due to a libusb bug, which Andrei is working on. Andrei also mumbled something about porting libdpfp to Windows, which would be rather interesting.
