Core Algorithms • Image Enhancement (under study phase) Filtering: Gabor Filter • Thinning: Hilditch Algorithm • Matching: Cross-correlation Algorithm
Completed Activities: • Thinning Algorithm: used for single line representation of fingerprint ridges for properly sampled version of fingerprint images. • Matching: Cross-correlation based imagematching (minutia-based matching)
Testing & Trials • Runs successfully for properly enhanced images/oriented images. • Fails for low resolution images where orientation is changed.
Problems • Dryness of skin ,worn-out ridges, skin disease, sweat, dirt and humidity in air all contribute to the non-ideal contact situations. • The variation of the pressure over the region of contact of the finger and the scanner. • Image acquisition and binarization of the acquired image has been difficult.
Motivation behind it • Finger-print recognition is used in various systems for Verification, Identification etc. • Recognizing manually can be very time consuming and costly. • There are systems already in use which use similar technology and a lot of research is going on to improve the technique.
