2- To solve the problem of limited documentation and
example code available on the subject of
biometrics. - Research that is done in this field can not
directly be used in an application the
programmer must develop the code themselves using
the research as a guide.

4- Problems associated with commercial SDKs
(Software Development Kits)
- Fingerprints are matching by comparing minutia
points - Two basic types of minutia points
Line ending Line branching
- Fingerprint verification vs fingerprint
recognition - Verification systems need to have more accuracy
- Recognition system must be able to process many
prints quickly
This project is a verification system
5- C\C Compiler
- Basic Text editor or Development IDE
- Hex editor
- Image manipulation program

7 Edge Detection with Logarithm Algorithm
8Thinning with Skeletierungs Algorithm
Breaks found
Final rewritten thin
9Match Part 1 Shifting
- Move the verifying print vertically and
horizontal to find the spot were the most
pixels line up. A true match will have a certain
percentage line up.
Lines up Does not line up
10Match Part 2 Minutia Matching
Line Branching
Line Ending
11My data has shown that this system is not 100
accurate, but no prints that were not suppose to
pass did. With a little bit of tuning the
accuracy of the system can be easily improved.
Also most of the goals for the project have been
met, with the exception of speed. As for speed, a
revision of Thin() and Match_Part1() are required
to optimize these functions. Unfortunately
smudged prints still cannot be matched without
further correction of the images. Overall the
project was a success and continued work will
only improve upon it.
12- Image manipulation including scaling and
rotation - Faster Thinning
- Faster Matching Part1
- Design Embedded System
- Correction of smudged and other imperfections in
images
