Can NFIQ2 compare iso files? #338

Closed xellDart closed 2 years ago

xellDart commented 2 years ago

I use NFIQ library to calculate NFIQ2 Score and generate iso files using

err = fjfx_create_fmd_from_raw(image, 500, height, width, FJFX_FMD_ISO_19794_2_2005, tmpl, &size);...

Can I compare two iso files (two different fingerprints) using this library?

Thanks

This is not an NFIQ 2 API method. The NFIQ 2 API only supports generating quality from decompressed grayscale 8-bit 500 PPI images and does not decode any image codecs. The NFIQ 2 CLI does support this type of parsing, so look at that code for more assistance.
