I need to convert bitmaps files with fingerprints to ISO/IEC 19794-2 templates. The source images have a resolution of 320x480 pixels.
Currently i use SourceAFIS (.Net library) for this task. It requires about 1-3 seconds on the RaspberryPi to do this job. The tool runs as service which means i do not always restart it. My current usecase requires (soft-)realtime and everything runs very fast, except for this conversion.
I don't know if this conversion is just very expensive or if the algorithm is not optimal implemented. It works very well, but it is just a bit slow.
Maybe someone else knows a very fast and simple command line tool which does exactly convert bitmap files to ISO/IEC 19794-2 templates?
Thank you very much
National Institute of Standards and Technology (NIST) have BiomDI, opensource tools for fingerprint operations in C: http://www.nist.gov/itl/iad/ig/biomdi.cfm
