Изобретение относится к распознаванию и кодированию отпечатков папиллярных узоров, используется в автоматизированных дактилоскопических информационных системах. Цель изобретения - представление метода определения особенностей отпечатка папиллярного узора путем последовательного вычисления потоков особенностей из общей структуры потоков папиллярных линий, определения вероятности непревышения отклонения определенной особенности от истинного положения. Сущность изобретения заключается в том, что при формировании массива выделенных характерных линий в окрестностях точки определяют направление потока папиллярных линий, производят сглаживание картины потоков заменой значения направления потоков на среднее из значений направлений потоков средних точек, определяют вероятное положение характерных признаков, вычисляют весовые функции, производят последовательное вычисление характерных признаков и находят надежность определения характерных признаков папиллярных узоров.The invention relates to the recognition and encoding of fingerprints of papillary patterns, is used in automated fingerprint information systems. The purpose of the invention is the introduction of a method for determining the features of the imprint of the papillary pattern by sequentially calculating the flow of features from the general structure of the flow of papillary lines, determining the probability of not exceeding the deviation of a particular feature from the true position. The essence of the invention lies in the fact that when forming an array of distinguished characteristic lines in the vicinity of a point, the flow direction of papillary lines is determined, the flow pattern is smoothed out by replacing the flow direction value with the average of the average flow direction values of the midpoints, the probable position of characteristic features is determined, weight functions are calculated, and weight functions are calculated sequential calculation of characteristic features and find the reliability of determining the characteristic features of papillary patterns.
