Convert finger print image to comparable template.

Question

I have a fingerprint scanner that gives me only a fingerprint image (its SDK does not provide any functions for “converting” them to a template and for comparing these templates). My question is which approach should be used: look for an SDK that provides functionality for converting and comparing images with fingerprints, or shpuld I write these algorithms myself (which seems complicated and time-consuming). If the first method is preferred, what is open source / paid sdk for this to work? Can you give me some links

My device is Verifier 300 LC.

Thanx in advance :)

Answer 1

There is free software for biometric images NBIS and libfprint based on it.

It seems that fingerprint image comparison can be easily developed, see this thread

There are also commercial libraries:

• VeriFinger SDK
• Griaule Fingerprint SDK
• Bio-Plugin SDK

Answer 2

I was looking for this conversion of a raw fingerprint image to the WSQ standard in java, and I found below useful. Hope this helps.

There are many programs available, you can start with NBIS , which has many ex tools: minutiae extraction tools ( mindtct ), bitmap image (JPG / PNG) in WSQ snd vice versa, etc., with NBIS.NET. Some problems arise when converting a 32bpp image to 16bppGrayScale or 8bppIndexed,

By examining NBIS samples, you can quickly learn and create your own custom FP compliance algorithm.
