Fingerprints: Orientation Free Minutiae Extraction and Using Distances between Minutiae for Identification and Verification
Fingerprint recognition has become a standard in both access control and forensics. This is because fingerprints are unique to an individual. While there are many ways in which a fingerprint can be recognised one of the most common is to look at the endings and splitting of the ridges. These are called minutiae. This research undertakes to improve upon existing methods used in all parts of a mi...
متن کاملA Reinforcement Learning Agent for Minutiae Extraction from Fingerprints
In this paper we show that reinforcement learning can be used for minutiae detection in fingerprint matching. Minutiae are characteristic features of fingerprints that determine their uniqueness. Classical approaches use a series of image processing steps for this task, but lack robustness because they are highly sensitive to noise and image quality. We propose a more robust approach, in which ...
متن کاملA Secondary Fingerprint Enhancement and Minutiae Extraction
In this paper, we introduce a new fingerprint enhancement algorithm which used FFT and Gaussian filter. FFT is applied on a block, of size 32x32 pixel and Gaussian filter is applied in each interconnection of each block. This make ridge smoothness and also reduce the “hairy” structure in the ridge when it is thinning. The experimental result shows that the implementation of FFT and Gaussian fil...
متن کاملAdaptive Fingerprint Image Enhancement with Minutiae Extraction
Fingerprint image enhancement is the basic and most required component of biometric verification system. This method proposes a fingerprint image enhancement and template based minutiae extraction techniques. For better enhancement the preprocessing stage includes global and local analysis. In the preprocessing and local analysis blocks, a nonlinear dynamic range adjustment method is used. In t...
متن کاملMinutiae Points Extraction using Biometric Fingerprint- Enhancement
Security mechanisms always insist the wide usage of fingerprints as common biometrics. The various features of the fingerprint like Minutiae points, Orientation, Reference points and arch‟s are always the focus of the concern. However, if the database of the stored fingerprints is hacked; the entire authentication system will be collapsed. Hence, to provide security to the security marks i.e. f...
