Abstract

PL W artykule przedstawiono metodę identyfikacji odcisków palców uzyskanych w procesie cyfrowego przetwarzania za pomocą urządzenia akwizycji obrazu opierającego swoją budowę na matrycy CCD (Charge Coupled Device). Algorytm identyfikujący odciski palców opiera swoje działanie na porównaniu docisków za pomocą popularnego kryterium służącego do oceny obrazów cyfrowych szczytowy błąd średniokwadratowy PMSE (Peak Mean Square Error).

EN Authors used a popular digital image quality assessment measure for fingerprint identification - Peak Mean Square Error (PMSE). Analysing the measure described by equation (1), it can be seen that the quantity of its indicators depends on the image content. It is very important because, due to this, it may be used for comparison of images with the use of an image of reference, like it is in identification of a user on the basis of the comparison of one's fingerprint with the model kept in the database. The method is to find common characteristics of both digital images. To do so, both images shall be divided into small segments with assignation of sequential numbers to them, as it is shown in fig. 2.
