An efficient algorithm for fingerprint preprocessing and ...
Feature Extraction The line based feature extraction algorithm [8] is used to find the features in the identified region of interest image. The line based feature extraction is briefed as follows. By using connected component analysis and the ridge tracing approach, all connected line segments with respect to all the pixels are determined....
Iris recognition using multiscale morphologic features ...
For feature extraction purpose we develop a novel feature extraction algorithm using multiscale morphology. Here multiscale top-hat transformation is used to extract structural/textural features. First, the multiscale morphologic operator is applied on normalized iris image using a line structuring element with different orientations and scales....
 Review and Evaluation of Fingerprint Singular Point ...
A number of fingerprint feature extraction algorithms have been formulated with their ... 1998). Others are Mathematical Morphology (Humbe et al., 2007), Minutiae Maps and Orientation Collinearity (Rajanna et al., 2009) and Adaptive ... the Mathematical Morphology Approach is susceptible to missed minutiae while the Adaptive Flow Orientation...
Minutiae Extraction from Fingerprint Images - a Review
The Hong’s algorithm inputs a fingerprint image and applies various steps for enhancement. Several other enhancement techniques present in literature are based on fuzzy logic and neural networks [33-40]. Choonwoo et al [41] presented a novel approach to enhance feature extraction for low quality fingerprint images using stochastic resonance (SR)....

An efficient algorithm for fingerprint preprocessing and ...
The pre-processed fingerprint after vertical orientation a nd core detection is applied to th e line based fingerprint feature extraction algorithm [8]. 3. Proposed Algorithm The block diagram shown in fig 1 demonstr ates the two stage processing (shown within the dotted box). For fingerprint image
Mathematical (diagnostic) algorithms in the digitization ...
Another method of noise reduction is by using mathematical morphology, which is a set theoretic approach that considers pixels in an image as the elements of a set. [2] , [9] , [10] Once the noise removal is done, the intensity distribution is looked in the smoothened image after this steps the light grained structures are segregated from the ...
