Convert Finger Print image to comparable template

Question

I have a finger print scanner which gives me only an image of finger-print(it's SDK doesn't provide any functionality for "converting" them into template and for comparing these templates). My question is which approach should I use: look for an SDK which does provide functionality for converting and comparing finger-print images, or shpuld I write these algorithms on my own(which seems hard and time consuming). If first method is preferred, What are open source/paid sdk's for that work? Can you give me some links

My device is Verifier 300 LC.

Thanx in advance :)

Answer 1

There is a free NBIS Biometric image software and libfprint library based on it.

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

There are commercial libraries available too:

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

Answer 2

There are many software available, You can start with NBIS which has many tools ex:minutiae extraction tools (mindtct), Bitmap Image (JPG/PNG) to WSQ snd vice versa, etc., With NBIS.NET Some trouble is during image conversion 32bpp image to 16bppGrayScale or 8bppIndexed,

By learning from NBIS samples you can quickly learn and create your own proprietary FP matching algorithm.
