scan technologies are based on Minutiae. Minutia based techniques represent the fingerprint by its local features, like terminations and bifurcations [46-80]. Two fingerprints match if their minutiae points match. This approach has been intensively studied, also is the backbone of the current available fingerprint recognition products.
After minutiae extraction with two methods by thinning and minutiae making points, fingerprint need to matches the submitted sample with templates (minutiae). A post-processing is used to removable any false minutiae after extraction done. Finally, fingerprint need to determine whether the identity ... Fingerprint Extraction Minutiae Points.
Minutiae feature extraction and matching are not only two crucial tasks for identifying fingerprints, but also play an eminent role as core components of automated fingerprint recognition (AFR) systems, which first focus primarily on the identification and description of the salient minutiae points that impart individuality to each fingerprint and differentiate one fingerprint from another ...

A ridge bifurcation is defined as the point where a ridge forks or diverges into branch ridges. Collectively, these features are called minutiae. Most of the fingerprint extraction and matching techniques restrict the set of features to two types of minutiae: ridge endings and ridge bifurcations, as shown in Fig. 3. A good quality fingerprint ...
Finally the minutiae are extracted from the thinned ridges based on the number of crossings and a post processing step applied to remove spurious minutiae. 4.2.2 Fuzzy techniques for minutiae extraction from gray level images Some fuzzy techniques have also been suggested in literature to extract minutiae from gray scale images directly.
It is difficult to extract only genuine minutiae from fingerprints. Enhancement techniques are being used as preprocessing methods for minutiae extraction. The fingerprint enhancement is a challenging process. To overcome the adverse effect caused by spurious minutiae in fingerprint matching, a new method for fingerprint enhancement is proposed.
However, fingerprint images get degraded and corrupted due to variations in skin and impression conditions. Thus, image enhancement techniques are employed prior to minutiae extraction. A critical step in automatic fingerprint matching is to reliably extract minutiae from the input fingerprint images.
image before the minutiae extraction. The results of thinning are shown in the figure: Figure 7. Thinned image 4.4. Minutiae Marking After the fingerprint image is thinned now it is easier to extract the minutiae points. To extract minutiae features this paper uses the crossing number concept. A
Abstract—Automatic and reliable extraction of the minutiae from fingerprint images is a critical process in fingerprint matching and a main preprocess for this stage is Thinning. There are a lot of algorithms for fingerprint thinning procedure. All of the previously proposed thinning methods try to thin

B. Minutiae extraction Minutiae extraction using the skeleton image, the most commonly employed method that is used for minutiae extraction is the Crossing Number (CN) concept [19, 29, and 30]. In this method, a window of 3x3 pixels is used to examine the local neighbourhood of each pixel in the image and the CN value is computed as

achieve good minutiae extraction in fingerprints with varying quality, pre-processing in form of image enhancement and binarization is first applied on fingerprints before they are evaluated. Many methods have been combined to build a minutia extractor and a minutia matcher. Minutia-marking with false minutiae removal methods are used in the work.
novel algorithm of fingerprint minutia extraction is proposed in this paper: The algorithm work on the thinned binary image of the fingerprint, in order to eliminate the false minutiae.The implementation of research work is done in .Net platform using custom fingerprint database of 100 images of 25 users.
