Fingerprint Orientation Field Enhancementmage preprocessing methods used in automatic fingerprint identification systems (AFIS). The most popular, gradient-based method is very sensitive to noise (image quality). Proposed algorithmis an application of gradient-basedmethod combined with more resistant to noise pixel-alignment-basedmethod. E

Lip Print Recognition Based on Mean Differences Similarity Measuresubjected to the Hough transform. As a result a collection of line segments approximating the lip print pattern is obtained. Each segment is described by its length, angle and midpoint coordinates. Lip prints are compared using the mean differences similarity measure. Presented studies tested the im

Human Vein Pattern Correlation - A Comparison of Segmentation Methods proposed by authors in their previous article are compared with the often used local thresholding algorithm. These methods are evaluated using results of classification performed by a correlation algorithm. Evaluation was carried out on 400 collected images, and shows that proposed methods are wort

Conceptual Design with the Use of Graph-Based Structures language is composed of design diagrams. A symbolic representation of design structures in terms of ontological objects and relations between them is defined, and then mapped into diagrams by a given realization. Diagrams are automatically transformed into the corresponding graph-based data structu

Estimation of Tolerance Relation on the Basis of Pairwise Comparisonserrors - developed by the author - are discussed in the paper. Two types of comparisons are considered. The first type (binary) answers the question whether a pair of elements belongs to intersection of two or more subsets. The second type (multivalent) expresses the number of subsets of intersectio

Evaluation of Reliability of a Decision-Making Process Based on Pattern Recognition computation machines, i.e. computers, assist people in making decisions; in some particular cases, computers are even able to make these decisions themselves. There are, admittedly, many situations, i.e. in flight control, airport traffic, or biomedical data analysis, where even decisions made by t

Prototype Extraction of a Single-Class Area for the Condensed 1-NN Rulee is counted. Starting with samples with the highest value of the measure, each sample and all its voters (which constitute single-class area) are condensed in one averaged prototype-sample. The algorithm is tested on nine well-known datasets and compared with Jozwik’s condensation methods.
