ANSI/NIST-ITL 1-2000 #26

Open aptinis7 opened 2 months ago

aptinis7 commented 2 months ago

I would like to inquire if SourceAfis includes any functionality that allows it to read fingerprint images from NIST files and subsequently compare them with other fingerprint data."

Let me know if you'd like any further adjustments

robertvazan commented 2 months ago

What do you mean by NIST files? ANSI-378?

ANSI/NIST-ITL 1-2000

robertvazan commented 2 months ago

SourceAFIS can read images in grayscale and WSQ (in some ports of SourceAFIS) formats that are embedded in ANSI/NIST-ITL 1-2000, but no version of SourceAFIS can unpack them from ANSI/NIST-ITL 1-2000 container. ANSI/NIST-ITL 1-2000 is an open standard though, so it could be implemented in the future.

thank you ! . i have one more quiestion i compare 2 fingerprints from those 2 datasets and i get match beetween FVC2002 DB1 B and FVC2002 DB2 B and to be more specific \DB1_B\101_3.tif"; with \DB2_B\101_4.tif" im wondering if this is the deisred result. thanks in advance

robertvazan commented 2 months ago

DB1 and DB2 of FVC2002 reuse participants. The match is correct.

aptinis7 commented 2 months ago

Thank you , DB3 and DB4 tha same participants also ?

robertvazan commented 2 months ago

You should run deduplication if you want to blend test datasets. There are many overlaps. DB3 and DB4 are unique though, AFAIK.

thank you robert apriciate it :)
